Bug Report - Maven fight bug

Today while fighting normal Maven I encountered the following bug:
During the 3rd ad phase when the nucleus goes in the middle an summons bosses, it chose Melur Thornmaul / Ersi, Mother of Thorns (purple boss from Bramble valley / Harvest). This boss then created his vine wall (the straight corridor) which cannot be crossed. Even after disappearing the game still thought it was there, and couldnt be crossed and f* up the movement of my character completly. Nucleus was killed with no problem and the last Maven phase started, which again, still was calculating this corridor. After not being able to complete the first memory game (due to impossible movement) I died. I tried again, still there. I relogged, still there. I tried to let it kill me again and go back in, still there.

So at this point it seems if that boss is summoned and uses the corridor, the fight is impossible.

I just saw this as well; please remove Melur Thornmaul from the boss pool or this fight can just roll unwinnable.

This just occurred to me and I died during nucleus and the nucleus went invincible as well. Bramble Valley boss present.
