While fighting along the edge of the arena (not where depicted in the screenshot), my NPC opponent suddenly quit the field as though my character were invisible or stealthing. I am not sure how this bug happened. I am guessing that there was some kind of line of sight issue?
It was disappointing nonetheless to spend resources on the fight, only to suddenly be unable to finish it.
