Maven Arena Bug

Reported the same issue under another thread:
https://www.pathofexile.com/forum/view-thread/3538857

"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.

Happened on Necro settlers just now 05/02

Only won the fight due to 6 portals and bleed....

Just happened today 2/17

Why is this still happening after 6 month ?!

This is still happening almost a year later...

Bump, cuz this just happened to me for the second time today! Maybe fix this super annoying bug before next week eh?

Happened to me today twice, it's not nice on a leaguestart please fix.

I've had this happen to me for three Mavin fights in a row. It makes the fight impossible and have wasted so much currency to try and kill her but I literally can't move my character at all. It is definitely the bear boss.
