Pre-video: I was mind controlled by a horde priest outside Grom'gol Base Camp, after breaking it I headed for the water (about 100 yards away). Upon reaching the water I didn't swim, instead I kept walking along the bottom. He killed me, leaving my corpse at the bottom, when I rezed on top of the water, since my corpse was at the bottom, I took fall damage and fell to the bottom of the water (still unable to swim). I then hearthed to Lights Hope Chapel...

Anyone else had similar issues? Is it ok for me to post as an issue on the Github server repo?
