Yes, I was doing all that. Lust and friendship with the best friend were at their peak, but the romance never went above 40 and the sex talks were constantly repeated, even when a certain event had already occurred, and I'm not talking about that last one. I know what you're talking about because in previous games I got there, and actually by loading a game from a previous version I was able to do it too, but from scratch it doesn't work for me.
I also know that I need to search for people through the people tab. What I never really checked was if it was after 8PM, I'll try that.
Thank you very much for answering, even if it doesn't work for me! For some reason my game doesn't seem to behave the same as the others, even on another computer and trying several different browsers. I'm supposed to be able to change roommates if I do the quick start, but I don't have that option anywhere either.
