It's unfortunate but the reason why a lot of these things don't have Nian Zhus is because they weren't coded to respect vanilla invisibility and they don't use the forge hook responsible for targeting. Due to the minor variations of mob AI, I wasn't able to make those Nian Zhus work without some serious whining or a forge PR I lack the confidence to write. Believe me, I tried :(

Hopefully I can revisit this down the road. I'll leave this open, as it is an intended revisit.

Yeah, makes sense.
