could you try uploading them to the gallery and place them in a new save for testing purposes to see if the couple has the same issue ?
Is one of the Sims a special NPCs ? Some premade ones can't be woohooed.
Also in the original save I also tried moving out the affected couple and moving them back in but that hasn't worked. There is one more adult sim in the household who I got a romantic partner (not a premade townie but a sim I made in create a sim and they have the option to woohoo.
Would you be willing to share your save with me ?
If so, please zip your saves folder and upload it somewhere like dropbox, googledrive or OneDrive and PM me the link.
I just PMed it to you now. Let me know if there's any issues! I just sent the specific save that's affected.
