Version: 1,17
Current software: Vanilla
Diff: Hard
Server was on spigot a few days ago when I noticed a difference on mob spawning, I changed it into vanilla and the mobs seems to be spawning well but I changed it into spigot then to vanilla again and now the mobs stopped spawning.
Problem:
The mobs ONLY spawn IF there are other people on the server and I am always alone on the server
