Pandaren questline

Is pandaren questline bugged somehow? I'm currently starting new char, and am at the quest Shu, the spirit of water. When I try to get to pools of reflections, it auto completes but I need to get the the pools to turn in the quest. However, there's a weird glitch that happens when I try to jump on the stones to pools. It teleports me to last stone every 0.5 secs. After like 10 mins of trying I managed to jump on the last stone but the last jump is impossible. Eventually the bug appears where you are floating above the stone and can't move. I can't HS, unstuck or die. Can't unstuck on site cause it says I have to complete faction choice questline. Alt+F4 doesn't do a thing. I've seen like 4,5 corpses on the stones and a few players that are confused what to do and just give up from further playing. Can someone address this, please?

EDIT: I managed to complete the quest, by dying and then finding my way around the wall as a spirit. Note that the path I found can only be taken as a spirit, so even though I managed to complete it, this is still an issue for other players.

nasty bug, sitting on it atm with my fatass - can't TP nor die

This exact thing has happened to me too. What do i do ?
