I play on Xbox One, no cheats, and recently had a random sim I'd been pursuing ask to be my girlfriend. My sim accepted and they're now dating. But I got no pop up to accept or decline, just an alert...
@PoptartJuniper I've had sims autonomously woohoo as well, always catches me off guard lol. And nope, no prior signs whatever. They were best friends and maxed out in the friendship and romantic bar. But no warning beforehand.
I only think I got the phone call regarding the proposal because I was listed as the NPCs best friend while being their girlfriend as well. So they ended up calling my sim to ask advice about my sim proposing..lmao.
