I setup temp shelters near an iron mine and they were within the hunter’s circle. When the shelters were completed, the hunter killed all of the deer and did not return to the hunter’s shack. When I removed the temp shelters, the hunter returned to normal (hunt one deer, collect the carcass, return to shack).
9/5/22 - Hunter is killing dear but not collecting the carcasses, saved game link below. (see screenshot of saved location)
