I have performed several graveyard tests in the Beta over last month.
June 13:
- Created a Gnome, died to wolves in Coldridge Valley, walked my ghost to the Kharanos spirit healer, and was rezzed in Coldridge Valley.
- Same as above, except I logged out at the Kharanos spirit healer, logged back in, and was rezzed back at Coldridge Valley.
- Died again, walked my ghost over the Dun Morogh/Wetlands mountain skip to Menethil Harbor, got on a ship, arrived in Darkshore as a ghost, walked to the Darkshore spirit healer, logged out and logged back in, was rezzed back at Coldridge Valley.

- Died in Coldridge Valley, walked my ghost over the Dun Morogh/Wetlands mountain skip to Menethil Harbor, got on a ship, arrived in Darkshore as a ghost, walked out into the ocean, had my ghost die to fatigue (which returned my ghost to Coldridge Valley but moved my corpse to Darkshore), did NOT rez at the spirit healer in Coldridge Valley, made another ghost run, took the boat to Darkshore, ran out into the water, rezzed at my fatigued corpse then swam back to the dock. Mission accomplished!
