RedMew/features/dump_offline_inventories.lua

-- This feature allows you to turn on anti-hoarding so that X minutes after a player leaves the game 
-- the resources in their inventory are returned to the teams

-- To do
-- What if player has no body when they leave?
-- What if players is kicked?
-- Do we want to allow donators and admins to keep their inventories as a perk? Or is that too pay to win?
