Describe the bug
PlayerStatusManagerClient holds a bad reference to Level with private Level lastLevel

Since there is a constant static instance of PlayerStatusManagerClient in WatutMod, this means there is always a leaky reference to the level, even if the player has left the server or changed dimensions.

Because lastLevel is only used as a reference for checking if the player has changed levels, I recommend replacing it with a WeakReference, as this would fix the memory leak without sacrificing functionality (if the reference has expired, then you're definitely not in the same level as before).
