Tsuitachi

So i was trying to solo Dorudugan and it took me almost 2 hours to bring him to so low hp, he was about to die. He used his pull ability and i moved away as usual but then my character hit some rocks while being pulled and got stuck mid-air. No matter what i did my character didn't respond and eventually i died. I spent so much time and made so many preparations to solo kill that boss only to die to this annoying bug ... This is frustrating to say the least
