So, my teen aged sim aged up to young adult. Soon after blowing candles I got a message that said my sim is now dating. The problem is that before aging up the sim was dating other sim that is couple of days younger. So my sim got bad reputation and maybe a furious boyfriend. The sim mentioned in the message was my sims partner at the prom and I am not sure did I answered yes when he ask would my sim date him but they never actually date. The game saw them as friends. I have never seen this before. If I remember correctly they should keep their relationships while aging up. Can somebody please explain what is happening? I thought that there is a bug either prom interaction or aging up. In any case it makes unwanted twist to the story.

EA is kind of 1950's regarding relations, so adults and teens don't mix. You would need to have Nraas mods or some "adult" type mods to allow adult/ teen romance. Hopefully, this works... @Igazor would know the Nraas mods for this. Most likely Master Controller and Woohooer can get it done, but I've had so many Nraas mods in my game since day 2 of playing, I can't bbe 100% sure that's all you need.

Maybe this is the reason. I still wonder why the game want give my sim a new boyfriend. But I think that I had young adult -teen affair once when I played without mods. (The young adult was teen first and there was no romantic interactions available.)

I have Nraas Master Controller and maybe I need it to get rid of the unwanted boyfriend.

It seems like a quirky game moment, adds unexpected drama!
