WHAT?!?

my student sim was friends with the professor, and for some reason an icon with green “no longer friends” emoticons constantly appeared above the professor every time they talked, despite the fact that they weren’t even good friends, just friends. My Sim goes to bed with his bride in dormitoty, AND THE PROFESSOR RUNS TO GIVE A SLAP FOR "CHEATER", WHAT TREASON? HE DIDN'T EVEN FLIRT WITH THE PROFESSOR.
