Maven Nucleus cannot be damaged

On second maven phase the nucleus became immune to damage and arena had invisible walls that I couldn't walk through.

bug report: 2,120,100,510

+1 same here, but also memory game cannot be played as it's unresponsive to any input https://www.pathofexile.com/forum/view-thread/3793644

Did you have Mother of Thorns (purple harvest boss) summoned during Nucleus phase? She creates vine walls that visually disappear but not physically. I posted a report earlier about this but after searching for similar bug reports it seems it may be a very old issue that has gone unaddressed.

Both the Bramble Valley bosses & Necropolis' Burtok were present.
However, the spherical bug was present since the very first map entrance, before Maven even activates for the fight.

It is connected for sure, but something else is also going on, since even three fights in, the memory game suddenly starts to fail entirely (no quadrant triggers any response from Maven).

This also just happened to me. The maven spawned Mother of thorns and had an unwalkable area where my character was glitching when i tried to walk into it.
