Having a problem, I think with entities syncing with the server and the client

The client log shoots out a massive about of these errors for every entity. Can supply more logs for info if needed

java.lang.IllegalStateException: Invalid entity data item type for field 15 on entity Bat['Bat'/4466, l='ClientLevel', x=60.37, y=-10.42, z=36.36]: old=false(class java.lang.Boolean), new={}(class net.minecraft.nbt.CompoundTag)

Your client and server disgaree on what data an entity (a bat) has.

The server thinks something is complicated data (NBT) while the client thinks it is a boolean.

 

Probably the only way to find the mod causing the problem is to experiment with removing mods until the error stops happening.

Backup your world(s) before removing mods.

Thank you, do you think it would be a server mod or client mod?

The thing sending the incorrect data is on the server. So it won't be a client only mod.
