My game is working except for one thing.. woohoo

I have a multi-generational game going and I am in the second generation of the family. Everything has worked except for the fact that my sim cannot woohoo with her romantic partner. Every time I have tried, they will talk about having woohoo, agree and then just stand there for a second. Their love levels go up but there is no indication that they have "woohoo-ed". I have no mods but I do a lot of game packs. I have tried repairing the game multiple times, but this is the only issue that persists. Has anyone else had a similar issue? This is literally the only issue and it was not happening before I had moved her out and into her own house. I have tried all of the woohoo options and none of them work. They are losing romantic satisfaction. I also tried cheats, and then resetting the game but nothing has worked thus far.
