I tried using your collection files, but, the store item collections don't show up. Jezzers work fine for me. Does anyone know why that would happen?
My best guess would be that mine were created with .packaged Store items, while the others are for regular or decrapified Store items.
Does this mean that sims3packs and packages have different resources? I prefer to download sims3packs so I can choose which files I want and then convert/combine the sims3packs into packages. It would be a shame if I couldn't use the collection files above because of the resources changing; I am loving how jezzer organized the store files.
