baby ariel breakup
So, I guess I have a pretty unique situation here. I added the SimDa dating app mod and had one of my sims go on a date. Baby Ariel was one of the sims that popped up on the dating screen, so I selected my sim to go on a date with her. They ended up becoming girlfriends, but since Baby Ariel is in an unknown world, she never showed up in the tab when I wanted to invite her over somewhere, so I could never further their relationship. Plus, I never saw her just walking around somewhere. I decided to have my sim date someone else, and they ended up getting engaged. When I went to marry the two of them, it said it wouldn't be appropriate for my sim to marry someone in their employ. I looked up how to fix it, and apparently one way to fix that bug is to have your sim break up with any other boyfriends/girlfriends they have. But anytime I click "Invite Sim to Current Lot" so that I can get Baby Ariel to that lot and then select my sim to break up with her, she never shows up as an option to invite over because she's in an unknown world. She's still in my sim's relationship tab, though.
How do I fix this? It's really frustrating since I can't get those two sims married until I break up with her. And cheats to modify their relationship don't work, since Baby Ariel doesn't have a last name. (Baby Ariel is her first name only- just my luck.)
