Typically this crash happens when interacting with an entity or block. This has also happened when falling into the water and triggering a raid. My friends and I love this mod and hope to continue playing! Index 79, 80, and 81 have been mentioned during all crashes.

Crash Report UUID: e589e8bd-5786-4fee-9c74-d8dac1fda39e
FML: 40.2
Forge: net.minecraftforge:40.2.0

Does the error happen randomly, or does it happen when something specific happens in-game?

Thank you for looking into this! My friends appreciate it also as we love the mod.

The crash seems random, but I've had it happen when:

Hitting an enemy
Clicking on a book/crafting table
Initiating a village raid
clicking on a door
Falling into water
Shearing a sheep
Trying to place a torch.

Well, right now, I'm having to build the infection system from Scratch for the THIRD TIME. Yeah, the old code got corrupt when updating the mod to MCreator 2022.3. So, I'm having to entirely rebuild the infection system. So, update may take a while!

Yikes! That sounds so frustrating! We'll be patient, though!
