"No problem," you think. "I'll simply run back to my corpse!" And so you try. But ... you can't find it. I mean, it's there somewhere, but you're on the wrong side of a moat, and ... well, you've never been here before. Wait, this doesn't look familiar at all ... I mean, it sorta looks familiar but ... it's different. You think you've seen that tree before but ... no, wait, it looks exactly like all the other trees around here. And ... dammit, your ghost just fell into this deep trench. Crap. You're nowhere near your corpse or the Spirit Healer. How the hell are you going to get out of this?
The answer: The brand new Return to Graveyard button. It's a new feature in the latest beta build, and it does exactly what you think it does.
