There appears to be a bug in the area where you fight the two bosses in the Chakhir strong hold. For this one, I was able to evade past the rubble in the arch at the back middle of the arena(I think this is where they emerge to start but could be mistaken.) I was eventually able to glitch through the wall back out into the arena but for several minutes it seemed like this wasn’t going to be the case. I have not tried to reproduce this outside of the fight, but I could do so if needed. In the fight you just have to dodge through the rubble and you should easily be able to clip through into the room on the other side.
