It appears few months ago, and since the’ I don’t jump to go throw these windows. But before it appears, I always jumped throw. But this is a really old bug like @neverplayserious said.

This game plays with your mind, there are walls where there aren’t and no walls where there are. This game is a world above us in terms of killing physics at every corner of the map.

I was able to see it times ago, but now I don’t see anything. It still exist but it’s due to setting I think, need few test on this bug.
