Thanks for your replies
It's appreciated.
I've managed to learn that both of my issues are still unhandled bugs on EA's part. Some players are even worse off than me, having their sims randomly changing also their non-werewolf appearance between transformations. Ugh. Furthermore, the eye glow apparently disappears after save and logout, but I've found a mod that at least counters this.
This is the first time I play a werewolf family, so I guess that's why I never noticed these problems with Supernatural.
