Sims only having sex on the bed (I have animations, and I have Sex interaction gameplay option ticked)

[Hunter019]

Funnily enough, this started after marrying a sim into my family who had no sexual orientation. She had male and female Sims marked as non-interested and wouldn't engage in sex, so I switched these in CAS, and she was able to do sex stuff. Now, everyone is unable to have sex even though they have the same interests. The only place sex still works is on the bed, which is very odd, because this wasn't a problem before. Has anyone else had this problem?

 

I tried creating a new save and using it, and it worked normally, which leads me to believe that my specific save file is the issue. Is there a way to resolve this issue? I have lots of creations and progress underway in my current save.
