Maven Arena Bug

Reported the same issue under another thread:

"Hello Team,

I just had a Maven fight that stacked a couple of bugs - I asusme due to one of the summons being Melur Thornmaul - leaving the vine wall - after the brain phase the arena acted as if they were still there though not visible (some projectiles did not pass through them either).

On the last phase - Maven bugged twice on the memory game getting stuck, not showing the tiles to go through, and just suddenly exploding.

Bug reference number 2 113 242 161.

- Unable to provide screenshot (invisible nature of the walls)."

Just wanted to weigh in and note just had same thing as well,
Came to make sure I wasn't crazy.

This feels real bad when you farm your way up through the steps to do the fight just to be told nah start again.

Bug rendering important progression fight entirely unpassable needs to be addressed and should be in known issues.

This JUST happened to me - please fix as im most certainly not a bosser but this is locking me behind getting all the voidstones..

Believe its to do with the bramble valley bosses that spawn as suggested from other players.
