Last time I played through i got 2 Parties in Bizarro Sephiroth fight.
Now that I played it again i got only choose 1 Party.
I think its pretty weird.

Usually you have to make 2 Parties in the fight and 3 characters get thrown away (depending that you got all), But for me i just got to choose 1 party and ALL the others except the three i chose got thrown away.

So anyone have any idea why this happens or what triggers it or is it random?
