Apex of filth bugged

In SC SSF, Act 3 normal, one layout of Apex of filth is bugged : one side is blocked by a wall as normal but the other side, after the second checkpoint in a v shape (the one on the right side of the map, with the entrance being on the left side of the map), leads to a spot with elements blocking the way forward. I have hugged every wall of the map to see if there was another way I had not seen, or if I could go through any part of the wall, but I am stuck on that particular layout.
I created another instance in which the layout was fine and I was able to get to the boss, but there is at least one layout in which the completion is impossible.
