Was on night time game. Had torch in hand which was assigned to slot 2. Torch was set to ON to see at night, when pressed hotkey 1 to change to axe, the torch assumed the position of the axe on the backpack and left a static "highlighted" spot where the torch would have been shining. In this case as it assumed position on backback the reflection was left on the roof. The spot didnt move, but there was a torch highlighted spot on the roof. Disappeared when returned back to torch.
