Tiny houses installed....chubby Sims?

[ShineXXX]

Hello. So I have been playing since years with the same Sims, I have the no fat/muscle mod so my Sims always stay just the way they were created. I installed Tiny Houses today (along with the patch EA released) and suddenly several of my Sims are much chubbier and broader? Their shoulders (and several other body parts) changed to broad, while the fat/muscle slider in CAS is still at lowest so it's a slider issue.

I REALLY don't want to fix all my Sims manually. I made a backup of my saves before launching the updated game.

 

Does anyone else experience this? And how to fix this?

 

Sim before

 

Sim now

 

Also this happens with every save I load so it can't be from swimming or anything. In the save file preview of the family I see my Sim with skinny shoulders, but once I load the save boom broad shoulders. Lower arms, butt, belly and other parts are also affected, but it's most visible with the shoulders.

Problem of broad/chubby Sims also persists with all mods (except WW) removed (and loading older saves), so it's not a mod conflict.

 

I also tested getting the original Sim from Tray, and placing them on a lot, when I do that they are as skinny as when I created them. So something happened to Sims that were in-game already only, but in that case, why doesn't loading older saves make a difference?

 

Edit: So I spent a lot of time fixing my Sims and making their bodies how they were before....I restart the game and they are chubby again?! What is this?
Basically, my edits to the Sims don't get saved, they revert to whatever after I restart. I have a different Sim I WANTED to be chubby, and after the restart he was skinny but with broad shoulders.
Edit 2: Just realized that merely leaving the household and going to worlds will reset the sliders.
