Mod Glitched under the map, I couldn't kill it with any spell or ability.  Even my dog couldn't kill it.  It stopped me from completing a part of the mission.  I couldn't replicate this bug (I tried hard).  This was also on "Soggy Swamp".  I have Attached a screenshot of this indecent. I am sorry that I would not provide a video or more details on the report (Didn't even notice till after it had already happened).
