Only host spawns mobs

Gamemode: survival

difficulty: Hard

cheats: false

mobspawning: true

when others join the world no mobs will spawn for them. Was not a problem in 1.20.4 or 1.20.32. If a member is in the end, no endermen will spawn until the host goes to the end. If Host is in end and members are in the overworld, no mobs will spawn for members in the overworld until the host is in the overworld. Again was not this way in 1.20.4 or 1.20.32.
I have videos, but too large to upload to this ticket.
