Re: Sims went from very satisfied to very unsatisfied after nothing happened
I've gotten those notices as well. But as far as I can tell, that's the way it is supposed to work. All my notices show up well after I've gotten the couple very satisfied, usually during a date. I haven't tried with couples in the same household thus far though. I've been playing a single sim, and all his dates were either NPCs or sims from other of my households. What I have noticed is that if you don't keep in touch and do romantic socials often enough to keep the romance going, you start to get those notices from sims that are not in the active household that your sim has had romance with. The way I avoid them is to keep the romance going by doing romance socials going on a semi regular basis. The way it looks to me is that system was set up for romance satisfaction to slowly decline over time and you will have to work at it to keep it going. And it seems that that romantic satisfaction is somewhat independent of the romance bar since there is the Beloved trait that will keep both the friendship and romance bars from ever going down. So, what I see, since the sim I have been playing has that trait, is that the romance bar stays maxed but the satisfaction goes down over time. So, I just have another date with the sim that the notice came from and get back to very satisfied.
Hope this helps.
