[GRO] Difficult family dynamic resets out of CAS

@crinrict I just tested a few things and found a bizarre solution. All family dynamics work for me, but just for this one specific family the difficult family dynamic did not work. I could save them in a new tray file or place them in a new save, no difference. However, they only bugged out while being a mermaid and werwolf respectively. In their original tray file, as normal sims, the difficult dynamic worked. Apparently something went wrong when they were transformed or while saving them as new tray file. So, I cloned both of them to create them as fresh sims but not lose any CAS process. That worked like a charm. Seems like this specific version of this specific household bugged out for some reason.
