I seem to be backwards - before the latest update, I could go into quest mode, although I only tried it once or twice. After the update, when I go into quest mode, instead of random adventures, I just get a different version of story mode, with the set villains, henchmen, etc. I've tried several things, including restarting my whole iPad. I think I have an iPad 3 ... I have not tried uninstalling and re-installing the game yet. I was afraid this would erase my saved parties.
I can't find anything resembling this issue anywhere else ... any suggestions?
