Description

Game crashes from a ticking entity. Booted up game with Improved Mobs Disabled and played for a few hours and it worked just fine.

Steps to reproduce

1. Boot up Minecraft
2. Play on a Singleplayer world
3. Wait for a zombie with certain conditons met to spawn
4. crash

Mods that might affect the issue

Several mods in the crash report modify or extend entity behavior and goals. Based on that, here are a few mods that could potentially be involved:

Improved Mobs: This mod specifically modifies mob AI, behavior, and difficulty, which could be causing the ticking entity error for zombies.
Ars Nouveau: This mod has several mixins related to entity and AI behavior, and it could be altering the zombie's behavior.
Botania: Botania has mixins related to entities and target goals, which may also influence how the zombie reacts in-game.
Artifacts: This mod also affects entity behaviors, adding unique mechanics that could potentially interfere with mob AI.
Spartan Weaponry: It has mixins related to zombies and other entities, which may be a source of conflict.

this is very strange... are you sure its caused by this mod? the part that is crashing i do not touch at all

Weird, then I am unsure. I have only been able to replicate the crash with improved mobs installed. Could it be another mod's interaction interfering with something Improved Mobs is doing with Zombies?

hmm not sure. try this approach:

1. Remove half the mods
2. Start the game
3. If issue persist go to 1. Else try with the other half
4. Continue till problem is found

this can find mod conflicts pretty fast. problem i would assume though is that this happens randomly right
