I'm currently playing with Thi who's one of the premade sims available in one of the new residential rentals with For Rent. She ended up falling in love with her property Owner Panya Li currently they are in a relationship, and I am trying to get him to move in. The option to ask him to join household doesn't show up on him so I did cheat and add him to the household to make sure that he's sold all the property's he supposedly owns and then I had him quit his job, I removed him from the family with the cheat and then the next time he came over the option to ask him to join my household had appeared. So I went through the motions, and I asked him to join my household and screen came up I added him to the family transferred over all his simoleons and then hit the check mark and the game just froze. It sat on this screen for an hour! I had to eventually force quit the game and now the option to ask him to join my household is gone unless I go through the whole motion again of adding him and then removing him and then actually asking him. But what I don't understand is why the option to ask him to join my household without cheating him in doesn't show? Is it because he was the property owner? I am so confused I just want this sim to be added to my household without cheats. Has anyone else been successful in romancing their property owner?
