Battle error: battle won't begin nor show battle char

You have 4 non-participating characters? Didn't expect that.

Get rid of Russell first, then add Ida, and finally remove the other three. You can't add someone to a party that's completely full already, you need at least one slot open. Currently Ida is failing to join your party, and then the other four are gone, resulting in a zero-person party... And I already mentioned what happens at that point, heh.
