Molten vault boss vs Rhoa mount lol

Was on the rhoa before the boss, and you get off the rhoa during the animation. Then the rhoa bugs out when going into the molten vault boss arena because during the animation there is nowhere for the rhoa to go and it just bugs out. And when you leave the arena too. You have to disable your rhoa skill and re-activate it because the rhoa just freezes. Bug report# 3643638733
