Am I missing something here? I've been dying to get those "lost" or "hidden" Uni wants into my game. I downloaded the second of the choices, unzipped, put all of them into a separate sub-folder in my downloads ("LTW Mods"), and then ran the game to test them out in-game. I have the Insimenator, so it's not hard to re-roll the LTW of any Sim. When I did 6 or 7 flips to see what would come up, I didn't see any changes to the originals, and I also didn't see the 4 Uni ones pop up.
