...character deleted...:(

So i reached level 16 and it said now your character has perma death...

And I was ok with that.

But then I checked my hunter and all were gone. Two hunters level 16 and a level 5 both gone. Left me with the free hunter lol

Is this a known glitch or to do with the free weekend ?

Or did I corrupt it !?

Bit annoyed as was having real fun...now need to start again :( (which I've done and it's still fun lol).
