Okay I already raged about this in another post but now that I have calmed down and review ed the footage I can give a guess on what specifically happened. Alright I was on a team running Aksis part two. We had been going through it and failing for over an hour so obviously bugs were inevitable at this point. We had finished three damage phases against Aksis at this point and had entered our fourth stun phase. We had managed stun him twice once in middle and once on right. For this third stun he moved over to left side where I was waiting for him. I was empowered so I ran right at him and did the same jump as always however rather than get over him I was bouncing off an invisible wall and failed to stun him because of it. My best guess is that the positioning of his middle leg on his left side (or just his whole body in general) did not register properly and so the physics related were in the wrong place. This is a bug that I believe will require attention as it makes stunning him impossible. Edit: I've uploaded the footage and will post the link below. I apologise for the yelling and for my language. I advise turning volume down a bit https://youtu.be/8vcukGLxYLw
