Hey guys,
So I've been playing for a while and I'm at Valley Seven. I saved at the saving point just before that boss, but then when I tried to load the save file (which states "Valley Seven - Cauldron 4") I'm instead put in a place called "The Windswept Mire", in which I've never been. There's nothing in that area but a frog in a pond which I can press x to talk to but nothing happens. Plus there are no random battles there as well, so I can't just kill myself and go back to Nine Wood Hills.
I tried using a teleport stone, but it just puts me to the side of the area (outside of the map bounds), and leaves me unable to move.

I'm basically stuck and I have zero ideas of what to do now.. Has anyone encountered that glitch before? Is my save file gone for good? =[
