I'm sorry this is quite late, I've not been able to get onto the forums.

These sims didn't have alien skin, and I don't think any changed to the 1st face, apart from the one with the business outfit and that was temporary.

I don't think the faceless bug is related, though it could be... anyway, what I ended up doing was wiping the neighbourhood and doing a shiny no townies or pets restart of it. 2 families and generations in, and everyone still has their faces. Related? No idea. But with daily backups, hopefully it'll stay like this Thanks for all your advice, though.

Thank you, I'll do that in future, then! (And I'm glad I've not gone insane XD)

The first sim I mentioned was created with a cat, but her face was fine. But her face was heavily edited inside CAS... Whether that has an effect on it or not, I don't know, but I'd rather be safe than sorry when it comes to faces I really didn't want

To start with, I've got all of the EPs, if that helps at all.

One of the face-changing incidents was when a CAS adult female set a uniform for her home business and wore it - it gave her a face which I think is the first template face in the (1st skintone) white adult female section. I kinda freaked out, told her to 'wear casual clothes' and her real face came back, so that was ok.

But the unsolved and unfixed ones are kinda annoying. She has twin children with her husband who live on the lot. The daughter resembles her, the son resembles his dad, but the daughter has dad's 'normal' ears and the son has mum's elf ears - well, had. He had them as a toddler and as a child. Then after a few days I was doing a 'change appearence' on him and I noticed that he no longer had elf ears (he was still a child - I don't know if he had them straight away after he grew up, though, as the hair covered it). Second unsolved: a townie I made was supposed to be Japanese and I made his face to look like that. However when he recently visited the business, I noticed that he had a completely different face. Eyes were still similar but the nose was completely different at least. All I can think of is that the business is a salon and he'd had makeovers both successful and not, but surely that shouldn't be changing his facial structure?

Another family was started in CAS. One guy with a 'default' face that I made and two dogs. I quite clearly remember putting that face on him after thinking about another one with a bigger chin and smaller eyes - I decided on the one I made and finished making him. I am sure that in the CAS screen he had this face. When I moved him and his pets onto a lot, I realised, when clicking on something and making a menu, he had that other face. This one could be down to me undoing something and not realising but I really, really doubt it - I do skin then face then everything else. I don't think there's any way I would have done contacts and makeup and eyebrows without realising it was the wrong face, but I suppose it is possible - but what it seems to me is that again, some poor sim's face changed on them for a reason I can't work out.

This is a fairly old neighbourhood but I did a deleteallcharacters before I made the two families living in it. I've made townies and, when visiting community lots, spawned NPCs, but really not enough to be causing problems (terrible things have happened before when 3 families are onto the 15th generation and everyone has siblings and there are lots and lots of townies and not much inbreeding but I recognise when that's happening and I don't think this is the problem here.)

Can anyone help me, please? I've not done a full reinstall because I don't want to unless it's necessary... and I've had plenty of problems in my game before that I've managed to at least sort-of fix, but I'm really stuck with this. Searches for 'face changes' or anything just tell me about plastic surgery or dna-editing or replacing templates, not this kind of madness
