Boss Disappeared t8 untainted paradise

Was cleaning t8 untainted paradise, Map Shows 0 Monster left, cant find boss after walking 20mins in each area around to see if the boss was somewhere hiding but it wasnt.
then my atlas failed and thats really annoying, can u please rework untainted paradise and make it great again, it also dont give from feeling the same bonus as in poe1 more like 10% or less, it feels like clunky to play and you are gaining much more xp with normal maps

guys make untainted paradise great again <3 ggg
