Stuck in Combat after Plutonia on VH, Iron Mutant

TItle says it all. FInished the final fight. Should be getting my achievement, but can’t exit combat. Can’t go back because my file saved after everything was dead and I remain in combat.

PLEASE apply some fix for this so I can get the achievement I worked hard for!

In terms of what may have triggered it, I killed the big MIMIR bot as the last mob, and its explosion bled out Bormin. Might be a clue for you.
