Bug Description

See "Steps to Reproduce"

Steps to Reproduce

Login with 1.8 with optifine installed (example forge or lunar)
Join the 1.16.5 server with ViaVersion-4.0.0-21w19a, ViaRewind-2.0.0 and ViaBackwards-4.0.0-21w19a
Die from a player

NPC, Players and your self are invisible now (it look like that : https://media.discordapp.net/attachments/767315429189222450/843864694989258772/Screenshot_6.png?width=1791&height=875 )
Reconnecting doesnt help. Only a server restart help.

Expected Behavior

No visible bug

Additional Server Info

Proxy: Flamecore without any protocol plugin
Server: Paper-1.16.5 - 629
Java 13 (and java 15 tested)

Filtered sent packets https://pastebin.com/BFsM2mBB
It happen only for the player: Betman1234 ( bc of the client )

Checklist

• Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. BungeeCord), not on both.
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried a build from https://ci.viaversion.com/ and the issue still persists.

Sounds like it's because you use a 5 year old client version with old mods :p
If you can reproduce it on a regular BungeeCord/Waterfall setup and without such rendering mods, we will reopen this (and move it to the ViaRewind tracker).

Yea I know its the newest client version :D
I reproduce it on a regular proxy setup without any mods in the forge client.
Please move it to ViaRewind if they can help.

Need to update my issue. It doesnt matter if forge or not. It happen to a lot of players. Example Lunar client. I think, because of optifine, because if we remove optifine from forge it work without problems.

Oke, I found it. This version patch the invisible bug https://ci.viaversion.com/view/ViaBackwards/job/ViaBackwards-DEV/238/.

Plugin version list:
ViaRewind-1.5.4-185 | vv Build-392 | vbackward Build-237 | work
ViaRewind-1.5.4-185 | vv Build-392 | vbackward Build-238 | failed

Can someone look over this? Better would be a new branch with reverse of these changes to test it again.

The commits from that build basically restore Vanilla behavior for respawns (which was previously broken for respawns in the same world for skin changers for example), so that's 100% on OptiFine - nothing we can fix, sorry. I'd suggest downgrading (or updating?) OptiFine to an earlier version or not using it.

As you’ve undoubtedly recognized- Optifine is the issue here. This issue has been brought up multiple times and it’s not something we will look into further as it works with vanilla or unmodified clients.

Wow, I'm disappointed. Why this project still exists? I switched to ViaVersion-3.2.1, ViaRewind-1.5.3 and ViaBackwards-3.2.0 and the bug is gone. But in this version is a other problem what I already reported it without success.

As I said- ViaVersion is made to support Vanilla or unmodified clients. If modifications break that then we won’t help. That’s always been the deal, we can’t make it right for everyone. Besides that, 1.8 is quite a few years out of date now and rarely anyone still contributes code to maintaining these legacy versions. We chose to keep the older versions around because if we didn’t that would just spark another project to add them back. We compromised on not fixing bugs ourselves anymore associated with legacy versions more or less- But we are still taking in contributions by the community for maintenance of these versions.

I'm pretty sure you know that the most Minecraft players use the "Mod" optifine. You guys have more experience to figure the problem out. I only can say it work with 3.2.1. There was a change what break it. I'm on your side, but in this case it breaks the gameplay immensely

Lol, imagine using quotation marks to call optifine a mod, it's a mod, and a pretty intrusive one at that, constantly breaking other mods.

Wow, it took me hours to find the broken commits. It's not a solution for the players. A setting to restore the old behavior would be the best. But I see, reporting issues to improve the project is pointless. Second example #280. I think I need to create a fork of the project. You guys can "fix" it in 10 minutes and I need hours for it. Perfect.

Reporting issues to a project is not pointless. Reporting issues that only occur with clients that deviate from vanilla behavior is low priority or ignorable - if the mod breaks and not vanilla, it's probably the mod's fault, and not ViaVersion's. See if Optifine has an issue tracker you can contact.

See #280 and a other issue, but i forgot the number

^ and as I said, the commits restore Vanilla behavior and will otherwise break a good number of plugins... including the Vanilla client. Either you choose a different OptiFine version (which I am almost certain will fix it), or you have to report broken respawn packet handling to OF, assuming you are using its latest version. The other issue you linked is due to Vanilla restrictions of older clients, and PS works in some cases - in others it doesn't (also considering PS works completely differently to Via internally and is based on a different concept of packet transformation).

In any case, you should drop the attitude if you have no idea of the client's inner workings and also drop the expectation of version translation to an 8 year old version to work flawlessly in all possible scenarios - that's plain and simply unrealistic.
