Fixed items such as Red Bean Porridge and Air Bubble from acting outside of their scopes (now Air Bubble acts only under water, for instance).
Fixed an exploit with expirable quests when accessing the cash shop, that would make them "unexpirable".
Tweaked storages, now showing up popup warnings to players under level 15 instead of using the chat text area.
Removed "One-of-a-kind" tag from Lilin's Ring (caused conflicts with the Agent E custom script).
Added a few more scrolls to Spindle's shop.
Implemented several minor drop data adjustments.
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.
