I just played a game of regular deadlock using mina and when facing off against the doorman he ulted me near some of the walls, after escaping his ult I found myself not only in the wall but most commands to unstick myself didnt work. From using the unstick button, disconnecting, jumping, using abilities, etc. didn't work. Eventually by crouching repeatably and phasing out with her 2nd ability I got out, the unstuck button needs to be optimized to get out of the environment quicker as that cost me the game as I couldn't reset much to the dismay of my team.
