Hello, I was working on a creative map which was working well so far (even if it was not finished). But since an update the monsters on this map (zombies and animals) disappear on their own.
To give specific details, I can’t see or hear them but I know they are there because if I stay still they can hit me because I lose health. If I put an appearance point next to their appearance point I can see them, they walk correctly for about ten seconds and then they disappear and are in the situation that I described previously.
What’s strange is that my creative map is divided into two parts of the map. On one there is no problem with the monsters but on the other (the first to have been created) they disappear.
I looked in my game settings and in my island settings but I can’t find any answers. So I think this is a bug.
If anyone has the answer that would be great, thank you 
Did you ever figure out this resolution? I’m having the same problem.
