- Added 0.1 second of delay on item removal when "medic_stack_mode" is set to 2. This is to prevent a bug in case if the item disappears too fast before a player can grab it.

- Simplified some scripts.

- Added a new feature: "allow_bots_to_stack_items". When enabled, bots can pick items from virtual inventory after using a healing item (currently it's still bugged, as bots can pick items infinitely even if the scripts are the same as player's. If you don't want bots to become OP as "Gods of Healing", disable this one).

- Added a new mechanism to pick the stacked items after giving pills/ adrenaline to other survivors.
