Err... problem!
Hate to say this because it may ruin your day; but I somehow managed to get 3 #2: Dark Ophelia, Valentine, and Arfo-Ninja all at the same time. It happened when I was executing the Genesis Project.
Order of events:
Afro-Ninja is the first that is on the #2 list. I saw him yelling "Help!" in the battle field so I quickly click him to fall back and click the deploy #2 button under the shield icon. I didn't lock the camera so when I look back, I didn't see Afro-Ninja on the field, the deploy icon, and there is also a icon of a skull at his picture on the recuit list.
Assuming that he's dead, I hire Valentine to protect my base instead. After a while I open the pastry/#2 list and saw a blank picture in the #2 list. I then, hire Dark Ophelia.
Just when I hire her and closed the menu bar, I see Afro-Ninja still slashing my enemies in the battle field. I called my #2 out and it seems that only Dark Ophelia respond to my commands. And when I scroll up a bit I could see Valentine's corspe fading away.
I guessed I've told my story. And assuming that this isn't a easter egg, plese fix this ASAP. Thanks in advance (and don't rush it, it would only cause more bugs); nice game through.
