Mermaid Tail Is Gone...?

Ever since the July 1 update, the bottom half of my mermaid sims have just...disappeared? Both in-game and in CAS.

I have 3 mermaid sims in my household and it's happening to 2 out of the 3.

This is happening with or with mods (i tried both). I am also playing on PC though i did notice this is an issue for some console players as well.
