How does the problem look like?
So I took a fight with a pack of Medusa Queens, defeated them and the battle was over.
Only that the creature was still there but it was a FEW in numbers. Should ve vanished for good.
NEVERMIND, the game actually crashed. Not sure what happened.
What exactly did you do to trigger it?
On which map it happened?
Island of Fire
A screenshot or video would be fantastic.
