After removing mods and adding them back in a few at a time and removing a few till Only one was left that resolved the crash. Without enderIO/core no crash.

Issue Description:

Modded FTB Unstable 1.10 pack and All the mods.

What happens:

When returning from Nether to over world the server crashes. When returning from AromaCore mining dim the server crashes. I have not tried other teleport systems. Player is also teleported to a spot under ground and suffocated to death.

What you expected to happen:

Not to crash :D

Steps to reproduce:

1. make a portal
2. go in the portal
3. try to return to the over world and crash
   ...

Affected Versions (Do not use "latest"):

• EnderIO: EnderIO-1.10.2-3.0.1.81_beta
• EnderCore: EnderCore-1.10.2-0.4.1.46-beta
• Minecraft: 1.10.2
• Forge: forge-1.10.2-12.18.1.2046-universal

More info. I am able to port over 100 times as to make sure the sample is valid (with no EnderIO). add the mod and core back in and crash 70-80% of the time (tried 15+ times ((sorry got tired and lost count))).

I'm going to start with just IO/Core and see if it is a conflict with other mods.
I'll keep this updated as I test.

Can't get a new world to crash today. maybe EnderCore-1.10.2-0.4.1.49-beta fixed the issue?
My original world is still borked, I just opted to make a new world load all my stuff into chest and on to disk in Refined Storage. I just copied the player files to the new server and seams well.

If the crashes pop back up I'll just set up RFtools teleports to/from the nether (High Tech Nether Portal could be a thing?!! :D).

If there is anything more for testing I can do let me know id be happy to help.

Test 1: IO/core only. No crash (10 portals in new chunks with 150+ teleports).
Test 2: testing update IO/Core with full pack (and updating the rabbit hole of mods):
Updated IO/Core, Forge and JEI: same results on crash.
Test 3: Updated All mods; same crash
Test 4: starting to add/remove mods leaving IO/core to see if i can track down the mod conflict.

yes, please. This isn't eio on its own.

We have a winner! err I found the conflict. deepresonance-1.10-1.2.1beta38.
Going to do some more testing just to make sure this is not a false positive.. or would it be a false negative?

More testing. So loading the world with only EnderIO/Core, mcjtylib, rftools/dim and deepresonance will not cause the crash. So... it looks like there is another mod(s) involved in the crash.

More testing on the way. Going to start adding the mods back in a few at a time till we get the crash again (and test with a few new portals in new chunks and old). Each test I will do 20-30 teleports/portals. NOTE: each step will be from the control world save resetting each step.

The Deep Resonance you use is outdated. Please update and test if this occurs again. The tank/fluid system was rewritten there

reread the post ^ there. #3 Test 3: Updated All mods; same crash

So anther observation; The crash can happen with E/IO or RFTools without the other being present. The common link is ElecCore.

probaby the same problem with other modpack: https://github.com/whatthedrunk/allthemods/issues/95
crash when returning to overworld this time via nether portal. i only want to link it here

I was doing my own testing and narrowed it down to EnderCore. Testing on an older world that has the problem. New world gen does not cause this issue. Also removing ElecCore did not effect the crashes in anyway for me. Hopefully this info can be of help. Also the Mekanism crash has been completely separate from this one for me, one is loading or unloading chunks caused by teleporting and has a fixed pipe location. This one is just teleporting I to the over world without any mekanism pipes.

Yea same here my new world I am using in my lets play has not crashed the server yet. I have been Discoed a few time but the server stayed up. Ziggy can I ask what world gen type you used on the affected server/client? Was it Quarks by chance?

It was normal BoP generation on All the Mods pack. As the world wasn't mine, I was just using it for testing the gripe, I do not know what version the world was generated on.

Is it still possible to reproduce this issue with a new world and the latest versions of each mod?

If not, it seems like a bug in one of the mods somehow 'broke' worlds in a way that isnt resolved by updating, but using the latest versions worls will no longer get 'broken'.

If this is the case I would close this issue.

If this occurs again using the most recent versions of the mods then please re-raise the issue with a new log. Thanks
