With the goblins stealing stuff from me right and center, I decided to fight back. While my guys were piling into them, I didn’t have much time to pay attention, but later I noticed this Oak Log near my town. A goblin had apparently stolen it, then dropped it as he fled from my footmen. As you can see, it somehow fails to have a loot command available, even though it’s outlined in red indicating that it is an enemy item and should be looted.
I’m aware of the Loot command on the menu bar of course, but this bug indicates a situation where ownership of an item has not been fully transferred somehow.
