I'm pretty experienced at moving around folders/files/mods/CC, but I'm not sure what to do here. I need to find some CC that is evidently a .sims3pack, but isn't visible in my launcher.

For context, I had two pairs of CC contacts in my game for the longest time. After I added some new stuff, removed some unwanted .packages, and installed some performance patches (Sims 3 Settings Setter and Sims 3 Performance Patch) the other day, which shouldn't have made any change to my installed CC, I went into CAS to find that those two contacts were gone. These have been in my game for ages, so I have no idea what the name or creator was for either of them, so I can't just redownload and reinstall. I've checked my personal downloads history on several CC sites and in my browser, no luck.

I couldn't find any .package files in my recent deletions that could possibly be the contacts, so I moved my /The Sims 3 folder out of /Electronic Arts and began running a backed up folder I saved two weeks ago, when the contacts were still appearing in my game. They appeared in CAS again when I ran this old folder. After checking for any packages using the method with NRaas Master Controller + Integration and then NRaas Packer, I couldn't find any packages in that Mods folder with the same instance and group number as those contacts, ruling out that they disappeared because of a .package I had since deleted.

So, I went through the launcher's installed Content List and looked for them. No contact lenses show up as installed content, and EA conveniently never created a search bar or sort options for the launcher, which would help a lot. Sigh.

My last idea was to take my DC Cache folder from the two-week old The Sims 3 folder and transplant it into the folder I'm currently playing with, since DC Cache folders hold onto your installed content. Then all I would need to do is reinstall any .sims3packs that I've installed since then and move along. I need to know a few things first:

• Would this bring my installed Content List from two week ago back to my new playthrough without breaking anything else?
• Do I need to bring over the old ccmerged file, replacing my newer one, from the old DC Backup folder in order for it to work?
• If I bring in the old ccmerged file, would that break any new .package files I've added to my Mods folder since two weeks ago (because there have been a lot)?
• Are there any other ways to hunt down these two specific items?

Going forward, I'm converting all my .sims3packs to .packages to avoid this mess, but I would really like to figure out a way to get the contacts back into my game. If anyone has any advice, I would appreciate it!
