When you take a closer look at the entity models on the bingo card, you can see that some of them twitch slightly (some a little more (marked by "*"), others less) for some reason, while they don't do so when spawned with no AI in the game world.

The twitching entities include at least:

• a dolphin
• a hoglin*
• a llama
• a piglin*
• a piglin brute*
• a rabbit
• a trader llama

This issue occurs on the following configuration (I didn't test other configs):

• Minecraft version: 1.16.4
• Bongo version: 1.0.4
• LibX version: 1.0.6
• Forge version: 35.1.4

The ones with the * will continue to do so because they'll do it as well when spawned in the overworld.

Piglins and hoglins spawned with no AI do not shake and do not turn into zombified piglins or zoglins. I had checked all living entities before I reported this issue :)

Ok then I might be able to fix it for those as well.

The ones with the * will continue to do so because they'll do it as well when spawned in the overworld. The other ones will get fixed.
