The following image happened to me the other night after the fight with the Ogre Daily Boss in Wrothgar. The Boss took my health down to 21% and then it just stuck there. No amount or type of healing recovered it any higher. When I took more damage, the bar would go down, then recover back up to 21% again and then remain there. I traveled to a Wayshrine within Wrothgar and it didn't change. Entered and exited buildings. The bar then finally reset after using a Wayshrine to go to Reaper's March.
