[OPEN] Woohoo partners rejecting woohoo

So I think for most of you, and I figure out something on my side, it happened many times for me, to have sims becoming woohoo partners and then getting involved romantically. Then sims start to reject. I think after a certain level of romance, they will reject if they are woohoo partner, so I tried to ''end woohoo partnership'' in friendly interaction, and then they were able to woohoo under normal romance category.

Not sure how it was implement in the game, but these are my observations and solution, since they are romantically involve and want to woohoo, no point to keep that woohoo partnership for friends... but it should not prevent woohoo to happen though, by all means.
