I have always added whatever patches I need after each EP. Last one I did was for Bon Voyage, but...the last two EP's I purchased and installed are actually collections. One was the Best of Business Collection (Open For Business, Fashions Stuff and Kitchen and Bath). I looked it up and evidently the patch was installed when they made it into the collection. But I can't find out any information on the other one I installed. It's the University Life collection (University, Ikea Home Stuff and Teen Style Stuff). Anyone know where I can find out about a patch for that, whether I need one or not and if I do...how to get it?
Unlike TS3, when they had a patch for TS2, it worked for all previous EPs. University was well before Open for Business, so you should be covered.
