This is a message from my unfortunate partner:
"I was in the World of Ruin, 15-20 hours into the game and powerlevelling. I decided to take on Leviathan, who killed my Lv. 29 characters in a single attack.
However, this is where the weird s#!t starts...I got the game over screen, screen went blank and then all of a sudden I was back in the World of Balance outside Narshe!
My characters are all on the same level (29-31), but my stats are higher than they were before I fought Leviathan. The game clock now reads 4:20 and I'm at the part where you have to search for Terra (beginning with going to Kohlingen, then Zozo, etc).
What the hell happened?! Did Leviathan transport me back in time? Has anyone else experienced this?
I'm playing the GBA version on the Visualboy Advance emulator, I had only one save file (the one I was playing on at the time I fought Leviathan and got transported back to the World of Balance). I am sooo confused, and I can't reload my old save state because I saved right before I encountered Leviathan. So I kinda just have to go with the flow "
WTF???!!
P.S. Oh and he doesn't have any of the items he had from before he fought Leviathan, he's back to having the items he had at that point in the World of Balance.
