Uber Maven - invisible wall

Fighting uber maven and fight was going very smooth was into 2nd phase fighting the big nucleus in the middle. It summoned 2 of the bear boss from Bramble valley (Melur Thornmaul) I believe. They put their walls down (similar to the sirus tunnel trap) I ignored them I phased the boss.

The walls disappeared but they were actually still there and blocking movement. This bugged the Maven out and she couldn't be hit at all. She would teleport away as she usually does then after a second immediately ping right back to the middle. She continued to use memory game after a while but just couldn't hit her at all as she would immediately teleport back to the middle and was stuck in a wall. I could see her using her spam blast ability but the projectiles were not visible (I assume they were just immediately hitting a wall as they weren't hitting me). Dying and coming back didn't change anything the invisible walls were still there.

I actually had this happen in normal Maven Ruthless Twice now. It's unfortunate that this particular bug is not a higher priority unlike a lot of random interference bugs like objects blocking doors mobs stuck inside Blights the list is Long for sure but this one is very game breaking. It's 100% that silly Bramble Valley Blighted red bear Boss in Brain phase. There are a few issues this boss has especially in the small arena apart from his vine ability that's for some reason just glitching out and creates invisible walls. Maybe people have been able to use movement skills but in Ruthless this is not an option. once you get him though you screwed for the rest of the fight id love to explain more but everything thats happening is invisible so I can only speculate on how bad the objects on the arena floor are but they will last the entire fight all phases from hence forth.

The same experience, the same bear boss during Maven fight places some invisible walls and you can not move or teleport.

Can you please fix this?? This is the 'harvest bear' that is causing this.
