What happened to me is now my most weirdest thing ever! But let's get this story from beginning:
My "mad scientist" sim (screened a few times in this topic) finally maxed Inventing, and after some time, finished his simbot. I decided to release him upon the world. But first surprise: He's shown in family tree as the creator's son! I continued playing, and almost forgot about him, but when I was trying to find other sim in relationship panel, I moused over the simbot. To my shock, he has a boyfriend! And he (the simbot) is employed as acrobat, while his BF is singer, and even have unflirty trait. To make this even stranger, from rough inspection I believe there are even no venues in Isla Paradiso unless you manually place them.
So a simbot my sim made is gay, managed to be in relationship with unflirty singer, and is acrobat himself, all that in town with no venues.
Go home EA story progression, you're drunk!
