Disappearing Track and Station Data/Dashboard not opening in some circumstances

Disappearing Track and Station Data/Dashboard not opening in some circumstances

Before reporting, I have confirmed that

This bug does not appear to be reported in the Issues page before.
This bug still exist in the latest version of the MTR Mod.
I have tested this in the official version of MTR, not a modified/custom/unofficial build.

Describe the Bug

I have 4 stations with trains running between them, whenever I open Minecraft, and sometimes when I am moving around the world, the track is not visible and all of the station indicators (LT signs and passenger information show nothing (see screenshot). Yet the trains continue to function. If I go to the middle station the track can usually be seen and if I then travel along the track, either on a passing train or manually, the track will appear in places where it was not visible before. I have stripped out all other mods and just run the MTR mods on their own but this does not fix the issue.

Can you please attach logs? Thanks.

Dickovski · Answer 2 · 2024-07-04T11:23:52.000Z

Further issues. Whenever I try to add another siding or platform the dashboard no longer works (right-click does nothing). This is also the case for the other dashboards as well. I tried setting up a cable car system, before setting up a siding I tested the dashboard, it worked, then I put a siding in place, the dashboard no longer functioned. This may not be connected to the previous disappearing track issue.

edwnhsu · Answer 3 · 2024-07-15T17:49:15.000Z

I also got the same problem :( Tried to connect rails, but the rails disappeared... Also right clicked the dashboard and nothing popped up

latest.log
Same issue here...
As soon as the tracks did disappear, i saved the game so you should find the errors near the end!

I hope this helps <3!

RealJaron · Answer 5 · 2024-07-12T12:43:21.000Z

When you move far away and then come back with spectator it sometimes fixes itself, but that shoulnd't be the solution... :)

Flain16 · Answer 6 · 2024-07-14T10:33:00.000Z

I have the same issue, can not open any dashboard at all. Altough Train running fine

WillTemeraire · Answer 7 · 2024-07-16T18:53:57.000Z

We have the same issue on a somewhat modded server. ~~Lines were running just fine until we restarted the server.~~
Edit: Apparently the lines were only working for me (I am hosting the server dedicated, so not on my system), not for other players.
The depots still update, but every line is down to 20km/h, the tracks are gone and we get seizure inducing teleportation issues while boarding/driving.

JustAKuba · Answer 8 · 2024-08-01T20:57:16.000Z

I have the same issue, but I noticed that it happens only at my largest station, where there are a lot of tracks and dynamic elements. It could be caused by slow CPU processing since there are no issues on small stops and my computer is not the strongest one...

Dickovski · Answer 9 · 2024-08-16T13:42:07.000Z

Don't think it can be a slow CPU, I have a very new PC with fast gaming processor and plenty of memory.

kettle-7 · Answer 10 · 2024-08-18T03:18:57.000Z

No it happens on fast CPUs too, it does seem to often be caused by problems with storage capacity but that's definitely not always the case.

NXevo · Answer 11 · 2024-09-01T13:53:14.000Z

Same issue here...

I have a dedicated Linux server only for the Server, which does not get turned off, but if I build some rails and then disconnect form the server, when I join back all rails are invisible and info panels in stations does not work.

However, the trains are running properly but with 20km speed, sometimes teleporting to the stations. The issue also happens without disconnecting from the server.

Interestingly, if I create new rails or replace the disappeared ones they are rendered in the world. Restarting client and server does not make any difference. Yesterday they appeared on their own while playing, today they have not appeared at all.

The bellow screenshots are from a large and busy station and a very small one thousands of blocks away.

Dickovski · Answer 12 · 2024-09-01T14:05:15.000Z

Still waiting to see if the bug fixes are coming, lots of people commenting on the issues that they've found but no answers coming back the other way. This is such a potentially brilliant mod that I keep on adding miles of track, stations, etc. in the hope that it will all be fixed at some point, hopefully not too long in the future...

Kenny-Hui · Answer 13 · 2024-09-02T05:18:18.000Z

Not a developer, but to the best of my knowledge, these problems are not really reproducible unfortunately (And neither on my side either, it seems to be running fine with a dedicated server)

It'd be curious to see which Modloader and Minecraft version all people here are running on.
If there's something in common, that would probably nail it down a bit.
(Also any client/server log would probably help as well)

888845 · Answer 16 · 2024-09-12T16:35:42.000Z

idk it says nullpointerexception on mine

Kenny-Hui · Answer 17 · 2024-09-08T19:26:29.000Z

From my understanding of the packet overflow issue:
When the data needed to be sent hits the packet size limit, MC Mappings automatically splits the packet, then sent to the client.
When the client receives it, it reads and increments the PacketBufferReceiver counter until all parts are received, after that the packet is constructed.

On specifically Forge 1.19.4 & Forge 1.20.1, for some reason on some system configuration, the packets received can be duplicated (So for example if the packet is split into two, the client receives the 1st packet twice, and the 2nd packet twice, total 4 times).
This resulted in the counter being incremented 4 times (1/2) (2/2) (3/2) (4/2)
When the counter reaches 2/2, it deems the packet-reading is finished, even though both packets are the content from 1st packet, and the packet data is therefore cut-off.

Can open the dashboard with no issue here, weird
Trains does seems to depart from the depot, but seems to be somewhat inconsistent

888845 · Answer 22 · 2024-09-21T16:41:30.000Z

This is a beta release which is not meant for production yet. If you are just a normal player without a strong desire for MTR 4's offering, please just consider using MTR 3.2.2 which is much more stable in-terms of having functionalities working. I think I've identified the bugs that could be causing this, but at the end of the day there's only 1 developer working on this mod.

which is??? (developer)

Had repeating NullPointerException on my server, behaved similarly to this report. Missing tracks, non-functioning dashboard, etc. Unfortunately I do not have the world file, as it was accidentally wiped due to an operator error (see issue/suggestion #962) but I do have the error stack by way of the server log:

This error repeated at least once a second.

Server was/is running Debian Linux - Minecraft 1.20.1, Fabric Loader 0.15.11, latest Beta 9 version of MTR - as part of a heavily modified version of the Quantum Freedom 2 modpack (to be clear, the pack was modified, not MTR or any of the mods linked to MTR).

This issue is for client-related errors
Please open a separate issue for that, thanks.

this is reported in 1.19.2 and it is appearing indefinitely

888845 · Answer 25 · 2024-09-20T14:46:03.000Z

Did another round of looking

It is reproducible with only MTR Mod installed

It only happens on Forge 1.19.4 and Forge 1.20.1

It is reproducible both in Singleplayer and client + dedicated server

Most of them have a common symptom, that the Dashboard cannot be opened.

Happens when packet need to be split due to size limit

Client only read the 1st packet

BROKEN IN 1.19.2

Kenny-Hui · Answer 28 · 2024-09-20T16:07:12.000Z

This is a beta release which is not meant for production yet. If you are just a normal player without a strong desire for MTR 4's offering, please just consider using MTR 3.2.2 which is much more stable in-terms of having functionalities working.
I think I've identified the bugs that could be causing this, but at the end of the day there's only 1 developer working on this mod.

888845 · Answer 29 · 2024-09-20T16:17:21.000Z

ok but fix this in the meantime

Kenny-Hui · Answer 31 · 2024-09-13T21:01:09.000Z

Can you test it on other Minecraft version and see if it works with the same copy of the world? (i.e. Forge 1.20.4, Fabric 1.19.4, Fabric 1.20.1 etc.)

888845 · Answer 32 · 2024-09-14T08:14:41.000Z

its hard because of technical reasons but I will try
note that world-changing datapacks (terralith dungeons and taverns etc) are still on and cannot be turned off
they are mostly still mods

888845 · Answer 33 · 2024-09-14T08:55:35.000Z

can I use a different mod loader because gdlauncher is broken on fabric

Kenny-Hui · Answer 34 · 2024-09-14T08:59:31.000Z

Primarily I'd like to see whether this is version-dependent or not, the more version you can test the better, if you can't get it working that's fine.

888845 · Answer 35 · 2024-09-14T09:03:39.000Z

I will test them on curseforge

888845 · Answer 36 · 2024-09-14T09:20:50.000Z

the problem is my biome and structure datapacks might need one version for example if I have 5 datapacks with 1.19.3 forge support one is not 1.19.3 forge support and the world cannot load

888845 · Answer 37 · 2024-09-14T09:32:58.000Z

so idk but if someone else can do it then it is appreciated

888845 · Answer 38 · 2024-09-14T09:33:38.000Z

but I can say it was the same on fabric, but on 3.22 mtr it was fine, different modloaders have the same problem

888845 · Answer 39 · 2024-09-14T15:06:48.000Z

needs to be a bug fix asap

888845 · Answer 40 · 2024-09-14T15:13:23.000Z

also when I import fanmade mtr maps to 4.00 it is the same after a while

Kenny-Hui · Answer 41 · 2024-09-14T15:43:57.000Z

Still don't know what caused it
I've tried migrating a MTR 3 world to MTR 4 and it works flawlessly here, using other's world also seems to work fine whereas they don't.
Whatever this bug is, it's probably somewhat system dependent. (Different computer have different results)

888845 · Answer 42 · 2024-09-14T16:28:44.000Z

wdym system dependent

888845 · Answer 43 · 2024-09-14T16:30:43.000Z

idk what else maybe I should do it on 3.2.2 but rail placement is bad

888845 · Answer 44 · 2024-09-14T16:50:07.000Z

maybe it is Unknown custom packet identifier: mtr:packet
with architectury api

888845 · Answer 45 · 2024-09-14T16:57:49.000Z

or this java.lang.NullPointerException: Cannot invoke "io.netty.buffer.ByteBuf.readChar()" because "this.byteBufArray[this.readIndex]" is null
without architectury api

888845 · Answer 46 · 2024-09-14T16:58:53.000Z

idk If @jonafanho was involved here and could make a bug fix

888845 · Answer 47 · 2024-09-14T17:16:15.000Z

maybe beta 9 will work

888845 · Answer 48 · 2024-09-14T17:23:56.000Z

no it is still the same problem in beta 9 :(

888845 · Answer 49 · 2024-09-15T08:12:32.000Z

I may know some solutions
chatgpt message
The error "Unknown custom packet identifier: mtr
" indicates that the Minecraft Transit Railway (MTR) mod is trying to send or receive a custom network packet that the game doesn't recognize.

Possible Causes:
Mod Version Mismatch: The MTR mod version you're using might not be compatible with the other mods or the version of Minecraft you're running.
Outdated Dependencies: The MTR mod might require specific dependencies, like Fabric API, to be up to date.
Server-Client Mismatch: If you're playing on a server, there could be a mismatch between the mods installed on the client and the server.
Steps to Fix:
Update the MTR Mod:

Ensure that you're using the latest version of the Minecraft Transit Railway (MTR) mod. Visit the mod's page and download the latest version compatible with your Minecraft version.
Update Fabric/Forge and Dependencies:

If you're using Fabric or Forge, ensure they are updated to the latest version, along with all required mod dependencies like Fabric API or Architectury.
Check for Mod Conflicts:

Ensure there are no conflicting mods that might interfere with MTR. Temporarily disable other mods to see if the error persists.
Server-Client Compatibility:

If you're on a server, make sure both the server and client have the exact same versions of MTR and its dependencies installed.
Reinstall Mods:

Try reinstalling the MTR mod and its dependencies to ensure there are no corrupted files.
By following these steps, you should be able to resolve the "unknown packet" issue with the MTR mod. Let me know if you need further assistance!

any next steps or is this it?

This error repeated at least once a second.

Server was/is running Debian Linux - Minecraft 1.20.1, Fabric Loader 0.15.11, latest Beta 9 version of MTR - as part of a heavily modified version of the Quantum Freedom 2 modpack (to be clear, the pack was modified, not MTR or any of the mods linked to MTR).

I dont think I had that but I will check

I can also reproduce it - downloaded my 1.16.5 server world and changed to 1.20.1 4.0 MTR and am playing the world on singleplayer. Was having the exact same issue as everyone here - tracks disappeared, can't open dashboard etc, however the lifts worked fine.

Have no idea if saying this has any value or if it's already know, I redownloaded the world from 1.16.5, but before I went into the world on 1.20.1 I went into the world's folder, the mtr folder, and deleted everything other than rails and lifts. Of course, this meant that all the routes, platforms, stations and what not were gone but when I went back into the world the majority of rails loaded successfully and I could open the dashboard again. Although, as stated before, this deleted everything such as the stations etc for obvious reasons; an inconvenience.

Deleting the depot, stations, sidings, platforms and stations folders alone makes the dashboard work again. Not sure if, if one were to recreate the lines, depots and stations, they would return to the bugged state, or if it is a product of the conversion.
