No. In fact, I'll never get that character. I'm not gonna take the risk.
I have never heard of a glitch like this or seen it. Contact support so they know about it. (You can use the green ? to do this).
I've actually had a berserkgirl cr mysteriously appear as I was levelling before, so this isn't just you. Unfortunately, she didn't choose to stay around, and my Mantiz returned =(
Same thing happened to me earlier, i wonder what's up with it!
This shouldnt be a topic it happens to everyone but its just probally a hint for prizes in character lvl up missions.....
I smell an Urban Legend then.
