FFVI: Divergent Paths

I don't know if anybody had this happen to them but going to the Fanatics Tower to get the Gem Box and when you get ambushed by the cultists, the ghost sprite doesn't appear at all and the boss battle doesn't initiate, so without a way to escape or even use the menu, the game is just soft locked. 

Also for me the Mog glitch didn't happen until after i finished two scenarios.  I did Sabin first, then Locke, and the third time around it happened, not sure of that helps.
