Ok ive had the sims 2, nightlife, ofb, and university
I see OFB in your list... so I did not imagine things did I...
And yes to your question if you have OFB install. Might be since Nightlife that it change, I am unsure. For sure if the code is NOT working anymore, look for a mod or patch to do the same thing.
Closing this topic now since it is about adult material.
