• AutoRegLib 1.6-47

Random ctd on minecraft startup. Sometimes it crush, sometimes the game starts and run normally.
The issue started after i update my mods collection with newer versions and new mods. Also, i delete mod "Ice and fire".
Update didnt touch quark, i did update only other mods.

Encountering the same error. Running Forge 35.1.28.

Resaving or deleting the config file allows the game to run correctly for a while.

So, i tested it with my server. I changed mods to mods from backup, 1 by 1... and the problem was in the last version of charm. When i install last Charm version, it runs fine once, and give error on the second run.
The solution - using charm-forge-1.16.4-2.1.9.

The solution - using charm-forge-1.16.4-2.1.9.

The pack I'm playing does not contain Charm. So sadly that is not the fix

Sorry for the delay. Just updated the server and client to 285. Client launched fine first try but server crashes every time (7 tries so far)

Ubuntu Server 20.04
Openjdk version "1.8.0_275"
Forge 1.16.4-35.1.28

Looks like this is some weird race condition? I really can't tell what's causing it. I'm going to try something that might solve it next release but I can't guarantee anything.

Requesting you test this with Quark 284 and the latest forge, let me know if it still crashes then.

Game fails to start using latest build.

Fixed, try 285

Does 285 work?

Should be fixed with 286.
