Serpent Queen Manassa Disappeared in Vapour Springs, Unable to Exit

Hello GGG Team,
I encountered a bug in Path of Exile 2 (Early Access, Patch 0.2.0) where the boss, Serpent Queen Manassa, disappeared during the fight in Vapour Springs, leaving me stuck in the boss room with no way to exit. Here are the details:
Area/Act: Vapour Springs

Boss: Serpent Queen Manassa

Character Class/Level: Huntress, Level 73

What Happened: I entered the boss room, and during the fight, Serpent Queen Manassa vanished without any death animation or loot drop. The room remained sealed, and no exit portal or door appeared. Using a town portal (T key) didn’t work, and logging out/relogging didn’t resolve the issue.

Steps Taken: I tried resetting the instance via the Waypoint, checking for hidden exits, and relogging, but none worked.

Platform: PC, Steam

This bug halted my progress, and I’d appreciate any guidance or fixes. Thank you for your hard work on PoE2!
Best regards,
