Inventory backup! :D When a player joins a game, his/her inventory are saved to harddrive before it is cleaned. When the player leaves the game the player gets all stuff back at the exact same slots as they used to be. And since the inventories are saved to harddrive the players won't loose their inventories if the server crashes/stops while they are in a match, when they rejoin the server, they will get their inventories back.
