In for my son when fighting Rhino she doesn't die. Any idea what the problem is and if there's a fix?

She is not from that gig. It can be bug. I did sport fight with her first then she didn't count as enemy while doing "For my son" (she was in lower part of boxing ring with friendly "green" status).

It's a bug.
Encountered a slightly different bug, when "for my son" was already done stealthy, meaning that everyone started attacking me, when I was trying to do the "Beat on the Brat" with Rhino in the ring instead.

First time Rhino wasn't beatable at all when we both got outside the ring, but a simple reload fixed it.
