should be up. she was my first mermaid maid in CAS. I'll try another and see if it happens 

@Naa45702 Checked your Sims and it seems that outfit was saved with the scales.

There seems to be something off with the link form function in CAS. You can make them wear scales in the human form if you link them. I'll test this on fresh Sim as well to see if it also happens.

EDIT: Yes it does.

Could you maybe adjust your report to reflect this ?

I'm a little confused.  It defaults to linked. Does unlinked make it work better?

@Naa45702 If you unlink the, then the scales are not transfered to the other form. You can also individually link each part if you like.

Talking about this: https://sims4.crinrict.com/eng/2019/06/changing-the-alternative-form-of-my-occult-sim-also-changes-the-normal-form/

it was a weird linking issue. I unlinked and I was able to fix it. 

I too unlinked mermaid with human form and that fixed it.  

I would like to add on to this that in my game, every time I load CAS the link option is re-activated. I deactivate it every time because of all the same issues above, I spent hours meticulously designing all 40+ human outfits for this character, but soon as I load CAS and forget to unlink the mermaid, then there goes some of my hard work. It's even changed things like Tattoos and other features, but definitely hair and clothes are all swapped around. The problem for me isn't just that the linking doesn't work as it seems to be intended, but also that it just refuses to stay off. Literally every time I load CAS it's back and now I have to be super conscious of it. Also wearing one-piece swimwear seems to confuse it heavily and it just picks something at random whether I like the look or not if linking is on and then it just changes both sides of the outfit. One time my sim went back to human form with a whole new top and no bottoms on (I do have a nude mod, but this would still just be her standard underwear I mean instead of the swimsuit she WAS wearing) because I had her transform while in a one-piece, and when I went to CAS, sure enough this odd flasher outfit replaced my one-piece swimsuit outfit, hair and all, so I had to rebuild it from scratch. (I have no pics or video to prove this so...just take my word please). Point is, I don't understand how the linking should work...but it clearly isn't like this.
