After owner uses /setmaxplayers, the maximum count shown to other players appears unchanged.

When the owner of a world uses /setmaxplayers to change the maximum player count of their world, it says it changed but the count actually stayed the same. This has been an ongoing issue like ever since I found out that the command existed.

Steps to reproduce:
1. Join a world with multiplayer enabled
2. Run "/setmaxplayers"
-Any number works

Observed Rrdult:
The maximum player count will remain the same.

Expected Result:
From the perspective of someone that can join the world, the player count remains at 8.
