Me and a couple friends were playing survival and finally got to the end. Well while we were in the end we noticed some weird behavior of the dragon and when he shot multiple dragon's breath charges and there would be no particle effects but we would still get damaged in the area. Ontop of that when there is multiple spots of dragons breath it would increase the damage between all areas shot. They were invisible and multiplying in damage. It also does it on other worlds. Bummer that we lost alot of crap because this game breaking bug.
