Ok, I used the PersistenceRequired tag. I hope it's going to work.
On Screenshot(5) another skeleton just disappeared when it was not visible on my screen.
Hey, as I accidentally come across this post, I want to give you a hint that you probably need to give more detailed information(do you play on wi-fi, is the host using wi-fi, what is the exact name of the error that comes up), since when the error occurs, did you manage to play together before, did you reinstall the game or harass the game files or did some weird activity?
Does it cause some technical issues or some weird visuality deformity that is unacceptable?
To me, the bedrock animation is more cool. What's your reason that it should be done like in java?
Wow, with the PersistenceRequired tag the mobs can't attack the player and skeletons have no bows in hands. How to fix that?
