Playing With the Digital Ouija Board

I was dinking around with my game last night and noticed an odd skins issue.

Okay, suddenly, a bunch of my Enayla custom skins will not show up selectable in the CAS screen. If I hit the randomize button, they will cycle in sometimes. However, when I select the custom skin option, they don't even show up at all. Only about half of them were showing up. However, in game, sims I had previously made using some of the non-selectable skins still had said skins.

Checking the literally dozens of Enayla custom eyes I have showed the same thing happening.

So, last night I went through and carefully started sorting through them, one by one. And weirdly, some of them were in my folder twice, but with slightly different names (one would be capitalized, one wouldn't be; or one would be the plain old vanilla name and one would be PixieDream-NC.package...) I have no idea where the extras came from. So, I removed ALL my Enayla skins and eyes (except for my defaults), and am painstakingly redownloading all of them with a checklist I made to make sure nothing gets duplicated.

I mean, I removed all the basic custom ones that corresponded to the ones that had been made defaults, I don't have any geneticized skins, it was most passing strange.

Anyway, any advice about this? Should I do anything with the cache files for the game or not? I'm open to any suggestions! I do have Free Time, but I removed all my hacks/CC before installing it, and only reinstalled the hacks that were approved/fixed for Free Time after that. (I have not patched my Free Time yet, and intend to use the MATY fixes for it... but they haven't been downloaded yet.)

My game groans with CC, but I've compressorized everything.

Weirdly, I dowloaded the new Wardrobe Wrangler last night, and re-townyfied my clothing so that Young Adults could conceivably wear it, and of course, only a tiny percentage of it is showing up in the YA CAS. I haven't had a chance to check yet if there are still issues with that aspect of the Wrangler, been on a horrible deadline at work.

EDIT TO ADD: Well, the "take everything out, redownload it and then put it back in" system seems to have fixed the CAS problem. Only issue? I lost the Enayla skin that Friedrich Gorey was wearing (and thus, his two progeny lost it as well...). It must have been one of her really really early ones that I first downloaded, and now isn't archived anywhere. (I grabbed everything over at InSim and MTS2.) RIP Friedrich's fishbelly white skin! I guess I can come up with an explanation for the legacy somehow. Ah well. At least the skins/eyes are all showing up in CAS now.
