Crashing in 1.12.2 (The Llama of Doom?)

My crash report:

crash-2018-06-29_02.52.16-server.txt

This happened while I was killing a llama with a noteblock hat from the Hats mod. If I recall correctly it spit at me and then my game crashed. I've tried rejoining the world 4 times and all times I'll hear the llama make a sound and then the game crashes. I have no mods that affect llamas. I was generating new chunks at the time and was in a bat morph from the Metamorph mod. I have 56 mods on and have encountered no problems at all besides this one with the mods. I have Optifine and Foamfix (mod that drastically lowers Minecraft's memory usage with no affect ingame or with graphics). If you need anymore information just ask and I apologize if I put too much info in this post, its 3:00 AM and I'm about to go to bed.

Also I do have a backup but if I had to resort to it I would lose 2-3 hours of progress and an epic underground portal room I made.

Thanks. Luckily they have a discord server so I can discuss there. The Llama of Doom can't crash me now! HAHAHAHAHA
