Im not sure if this is a known issue, but theres a sound bug, I have gotten it twice so far.
Its when you ready up in the preperation fase, the ready up sound keeps playing the whole encounter.
I uploaded a link with 5 minutes raw material that way you can fast forward and jump in the video however you want.
Im not sure how to recreate the sound bug, but it seems to me as if its in lobbies where people lose connection and if i ready up before the game is done loading, but im not sure.
