Lava Lake bug 2.27

Hello. Today I experienced a bug while fighting Lava Lake map boss. I can damage Kitava but the animation for Innocence and Sin don't work as intended and can't proceed to the next phase. I also can't leave arena so map was bricked sadly. Video footage below.

playing on: version is 3.27c Hotfix 1
I'm experiencing the same bug as was mentioned here.


I've got a t16 lava lake map maven witnessed with destructive play allocated.
I did not full clear the map, so it didn't spawn all three extra map bosses.
at least one extra boss did spawn (idk how many exactly).
a ritual spawned in the boss arena with a wildwood abomination.
I had a divine vessel in the map device for pantheon completion.

the bug is kitava attempts to grab Sin but sin stays floating in the air and does not move to kitava's hand (sin never enters his struggle animation, he remains in his idle animation).
kitava then gets stuck in his idle animation.
adds spawn in small batches every 10 or 20 seconds.

leaving the zone via a portal and re-entering resets the animation and kitava attempts to grab sin again (failing once more).
adds continue to spawn in small batches every 10 or 20 seconds.

exiting to character selection and then re-entering the map behaves the same as exiting via a portal.

throughout all of this, the maven continues to use her abilities. the abilities that add elements to the field work as intended (grasping vines, zappy beam balls, etc.). I cannot confirm if the abilities meant to affect the boss work, since kitava's health bar in not visible.



I assume one of maven's abilities is at fault, but idk which one. I want to say that she is twinning kitava, but according to mapsofexile the boss of lava lake is not twinnable...



I hope that's enough diagnostic data for the bug.
I never know how to end these messages...

I forgot to send a bug report command and a screenshot in the above post.
here's the screenshot:
