It seems like these green barrels everywhere having a messed up fall down animation when you shoot them, instead of being a physical prop, they just animate like they fall, sometimes even half under the ground.
Also, I'm not even sure this type of barrels do fall from a bullet shot. They usually explode or if it's not containing anything explosive, just get pierced by a bullet. {F17627}
Shoot in some of them at the airfield area
Voting down because of the completely wrong priority and severity class, this should be low / minor instead of high / major. Please reserve the major severity class to game-breaking bugs, this is just a visual glitch and thus minor issue with low priority.
You didn't have to vote down, because of priority, developers created different categories for that purpose, assuming that my category is "Visual-Environment" it's a pretty major bug in that area....
