Delete your cache folder in your WoW directory.

A simillar thing happened to me in Vashj'ir; the reason I think it happened was, because I was using the minimal client, and Vashj'ir couldnt load as fast as I was traveling. Therefore it threw me out (instakill from fall damage, even though I was swimming) right to the middle of Mulgore (idk why there, I guess cause ".unstuck" would port me there.

Either way, next time I swum through Vashj'ir I let it load first, and it worked fine.
