OK, so I found out after days of play in the flying fortresses and mine areas that my dragon stone has quit working. Major bummer!
Being an avid RPG'er, I have MANY save games to fall back on, so I incrementally regressed back to the last time the stone worked.
I finally land up at the point that I am about to enter Stone's arena for the first time....the last point that my DS worked. Upon entering the arena, no more working DS. Bummer again, as I can't leave the arena (obviously, without clearing the arena and defeating Stone) to check whether my stone has failed for good, or is it just disabled for the arena sequence.
According to my saves, the arena killed my stone the first time through, and it never worked again after that.
Is this a known bug, and is it being addressed my the developers? How quickly????
Thanks!
