Sims 2 combo packs like such as Double Deluxe or University Life are evil.They don't necessarily correspond to the EPs they contain, so whether or not mods will work with them is a crap shoot.The Store version apparently also has mod compatibility issues. Finally, contrary to what has been reported, I have seen no proof that the Ultimate Collection is based on the Apartment Life/Mansions & Gardens engine so I cannot claim any of my mods are compatible.
Sometime even though hackdiff shows no problems, there can be changes to other routines which affect these.
The further back you go, the more likely you will find some unanticipated problem.
I've found a particular problem that means many of my mods require Free Time or later even if I've said they are compatible further back.
I'm updating these as I find them, but there is no way I can track down all of them so some won't get fixed.
NEWS April 7, 2016 - It's come to my attention that people are having problems downloading my mods. All (or nearly all anyhow) of the Sims 2 mods here have been updated to work with Apartment Life and Mansions & Gardens.
