Description:

As soon as I enter my world which I've been playing for ~20 hours or so, I crash immediately with the log below. I tried making a new world and got the same crash. The mod that lets you go back to the splash screen said it's Soot and Abyssalcraft. I posted this on Soot's git as well just in case.

Crash report:

Affected versions ("latest" is NOT a version):

• Minecraft: 1.12.2
• Forge: 2815
• AbyssalCraft: 1.9.6

Latest log file for when the issue was present:

I restarted Minecraft and I think I lost the latest.

That seems to be on Soot's end. Try updating that mod (provided you're not already using the latest version of it) and see if that helps.
