You can use the whistle underwater in the howling fjord to call a griffin. Id just finished the "reagent pouch" quest and called it not really thinking and started to swim and it caught me about halfway. Placed me back on the crashed boat and i coulda hearthed but decided to see if i could jump back into reality.... i fell through the map XD lol 46000 soul ash gone..

im so sorry i dont have a screenshot i just sent it but if it helps i swam aroung the two sharks down there on a gnome death night i couldnt name my echoes.. but i called it and then realized and started swimming kinda south and it grabbed me about halfway. and put me on the boat but the ground was missing or rather the water and the "Azeroth" was grey like block but the ship was still there i decided to not waste my hearth by jumping out thinking it was graphics. But no the world was over
