Minecraft 1.15.2
Forge 31.2.47
Create 0.3

After updating Create from 0.2.4e to 0.3, I am getting a crash every time I try to enter a world (I've tried both existing and new worlds). Downgrading back to Creat 0.2.4e allows me to enter the world.

EDIT: I should mention that I get this crash on singleplayer worlds. I haven't tried it on a server yet.

Are you using Enigmatica 5 by any chance?

I think we're having the same issue.

No, I am not using Enigmatica 5. I'm playing my own custom pack: https://www.curseforge.com/minecraft/modpacks/the-new-adventure

This also happens when starting a server. I think it's mod incompatibility because running this mod in an empty server works fine. I haven't been able to figure out which mod is causing it though.

Try updating Jaopca.

I would have never thought to look at that mod.. That fixed it for me, thanks a bunch!

Updating JAOPCA solved the issue for me as well. Thanks for the tip!
