I just played around with the small barrel stack on palettes. Ahhhh classic Relic.
Light vehicles can shoot them and destroy them to a state where there is only a palette and bottom rings of the barrels left. At this point they still block pathing and shots.
I then blasted them with a medium tank. Nothing changed. They still block pathing and shots.
Running over them with a medium tank finally destroys them to the state of NOT blocking pathing and shots. However, they visually never change appearance. So they look identical when they block and when they do not block.
I am guessing there was supposed to be a 3rd model state or some other bug.
Is there a list of bugged objects and their issues? We really need one.
Yeah, I tried something similar today and got to the same conclusion. I spawned an ISU in the upper right field of the first photo. By mistake I first hit attack ground behind the car on the left. After a couple of shots the car was destroyed (actually leaving nothing) but the shots still got blocked.
Then shot across the barrels which blocked like 6 shots as well. Then I ran over everything with the ISU and after that none of the shots were blocked anymore... Funny.
