Sims 4 after new base game update - animal colour glitch

First time posting, and I hope someone can help with this.

I've recently updated the Sims 4 Base Game, and I've yet to test it out in full, but one jarring issue is that my playable family in the game now seems to have changed the colours of some of my animals, with the ginger cat and white dog now just one shade on full black, with no indication of features other than the eyes. It's so strange, and not a bug I've ever come across before. I've got the games on Origin, and I've done 3 repairs and nothing. I'll see if a complete computer restart will fix it, but is this something anyone else has experienced since the base game update?

I really want to try and avoid uninstalling as it will take forever with all the games, so please let me know if there's a fix for this.
