Legion Mobs in Stasis Appear in Maps Without Legion/Having Done the Encounter

I ran several maps with the Legion Scarab of Eternal Conflict and legion mobs in stasis started to appear in my maps where either: There were no legion encounters, or I hadn't even started an encounter. The mobs are unable to be damaged and are T-posing. Several copies of my character are also in the maps, some using my MTX and copying my actions, others T-posing and without MTX.

This started after major graphical bugs and slowdowns happened while clearing the Legion encounter e.g. the entire screen disappearing, left with a brown background.
