Xbox player here. The combistick is not showing up on the pause menu map after being thrown (I think this is a bug). It should have an icon just like the wild boars that have been killed so you can locate it. It also can get lodged in trees and thrown out of the playable area.
For those cases where it can’t be retrieved, can we get an auto return feature if the thing exits the playable area of the map. Maybe something timed in case it’s still in the map but out of reach. Loosing half your arsenal is very frustrating.
