Fixed slotMax function caching up dirtied player data.
Fixed many portals not supposed to warp players to "random spawnpoints".
Fixed Wind Walk not being cancellable by attacking.
Fixed issues with negative experience being distributed to characters
when killing a mob, rendering "Exp reset". Fixed chaos scroll behaving
oddly. Refactored debuff expirations to manage one list with registered
debuffs and expire times, thus lifting some load from the TimerManager.
Added concurrency protection on how World deals with parties. Thanks to
the DietStory dev team, fixed some issues with the MK maps.
Made NPCs now work properly on multiworld system. Solved multiple issues
regarding Player Shops not giving back items properly when owner exits.
Added restriction on changing channels at FM rooms, preventing shop
owner entering Cash Shop.
