Description

When the difficulty starts to go up, suddenly mobs starts to have some invisible body parts, we would only see the head of zombies flying or in single player I can only see the chest and arms. If this is a feature how do I turn it off and iff not were does it come from ?

Steps to reproduce

1. Step one launch the game and create a world
2. Spawn some zombies, they will have a full body

4. Increase the difficulty
5. Notice that the mobs starts to span with invisible parts ( consistent)

Mods that might affect the issue

No idea unfortunatly

Did you ever figure out what causes this? Have the same issue

@JMundorf Hey maybe you can share your mod list and we can see what mods we have in common

@Flemmli97 I tried with and without and it's this mod, after a few seconds in a world the body of the zombies are disepearing

@Flemmli97 It's happening right after the first difficulty increment is happening, wich in my case is 1 -> 1.1

Our mod list is way too huge to list out since it's an entire pack + a sizable amount of additional mods, but the issue on the server seems to have gone away once the server disabled improved mobs

only other thing i can think of is that some mods have some armor that are not meant to be worn by mobs.
try using WAILA or something or this mod to check what armor the mobs are wearing: https://www.curseforge.com/minecraft/mc-mods/mob-battle-mod

I have tested and found the issue to be an incompatibility between Alex's Caves and Improved mobs. When testing with only those two mods installed the zombies lose their heads. It also varies, sometimes its skeletons as a whole or pillagers. However, once a mob loses it limbs or body all mobs of that type are affected regardless of equipment.

Blacklisting all Alexs Caves items also appears to "fix" the issue. Just use F3 +T to reload all textures

i have the very same issue OMG i was trying to find this for so long, and yes, when i test this mod with alex caves i can replicate the same issue
