While looking at Stsin's cell page, I noticed:
Not one of my active brutes, but a long forgotten brute that I don't use since I didn't set a password.
(it was probably my first batch I made after Stsin, not knowing that if don't set password right away, will lose the ability later.)
Looks like others have been training her. I can see why, since she's not a bad brute at that level and has a wolf. Even gained a rank. She even has a good amount of pupils not from me. Thanks.
And you know what's embarrassing about this? She has more victories than any of my brutes. Someone must be using her daily. I slack too much with my own brutes with the arenas.
