Rare archer abomination stuck in floor untargetable bricking the map completion

There is a not so rare thing when a rare archer abomination is stuck in the floor, it happened to me and my friend as well with the very same type of unit.
It is untargetable but shoots at the player but since it's a rare cant complete the map. My map is on sulphur caverns dont think it matters tho.

Picture is zoomed in so GGG might know the minion.
Not a game breaking bug just irritating.
Good game keep up the good work GGG and i'm looking for next season in PoE 1 ;)

I experienced the same bug - Sulphuric Caverns map. Rare could target/damage me, but I couldn't use any ability to attack/damage mob.

Tried porting out and back in a few times, no change.
