Game crashes after starting single game

[kelirious]

Bug Description

I played single player for about 5 weeks, sometimes switching the game on LAN to play with a girlfriend. Today, after turning on the game via LAN, the game crashed. After this problem I can no longer enter the single player game. I've tried reinstalling minecraft, tried allocating more/less RAM, tried backups, but still nothing helps. In the crash logs he writes about an error in the server, as I understand it, but I don’t understand what exactly the error is. In the game, I'm in the third era and have completed the Solar Tower from Immersive Enginering, and have also just started extracting liquid fuel, if that has any value in solving the problem.

Did this behavior use to work in the previous version?

yes

This is a completely different issue to #4818, please stop commenting there.

It looks like this is a problem with CB Multipart.

You could try updating that mod to this version.

You will probably also need to update CodeChicken Library.

This may cause breakages and I am not able to test this today.

@sam-kirby so i updated both of these mods, but they required an update to Minecraft Forge. After updating Forge, I transferred all the mods to the folder with the new Forge and Minecraft began to crash at the stage of loading mods

It seems you're playing a really old version of this pack, the latest version (v3.2.3) uses the last version of Forge to be released for 1.12.2 (2860) whilst you have 2707.

We do not support old versions, so please update. This may already be fixed.
