Enchantress Dies in Rift --> Enemy Follows for Rest of Floor

Nintendo Switch

Rift and Greater Rift, follower (Enchantress) dies results in a phantom enemy (who killed the Enchantress?) following main character for the rest of the floor. I have a pic of Urshi, main character the phantom enemy that keeps on hitting me not allowing me to upgrade leg gems. If you think about it, after Urshi appears there should be NO enemies in the greater rift, right?!

This phantom enemy occurs from time to time for me. Not sure I can trace it to the follower dying, as my followers always hsve the follower cannot die token.

I can reccomend teleporting to town and then back into the rift, as this seems to also remove all enemies.
