The twins bug
I had a match where I couldn't unbind victor. I would press the ability button, which was M2 and it would lock me in place as it normally does but it doesn't go further.
(Also, there is a bug with The blight, that I don't know if BHVR has taken into observation, but sometimes, after you use your ability, the game doesn't show you the prompt to go into a rush, nor does it work until you press M1. I don't have logs or a video about it, but I wanted to let you know)
