Just an update - all patterns are now available as sims3pack files.
Techno-babble:For anyone who likes/prefers the .package method, these
must be installed as sims3packs, otherwise they will not work, because CAP does not give new patterns new Instance IDs. I found this out the hard way, and have done a lot of research into it, and a whole lot of stuffing around. If you would like them to be installed as .package files, you will need to open each .package file and rename the _img resources and give them new IDs, and then update the _XML to reflect the changes.
