Any of those "packages feature names that would make Billy Gates' error code producers proud" (32 character hexadecimal file names) that don't have a type are most likely rogue outdated mods you picked up from lot downloads.
This should narrow down your haystack.
I found it already. But it's not necesarily rogue downloads. It's also clothing and the likes. When I created an item in the body shop, it also looks that way, and since I'm no modder they're only photoshopped texture works.
But there's another error:

Curious, since I never installed anything influencing wants. Also it happens with different Sims, different skins. And it only happens with female sims. Insimenator is the last version, compatible with AL.
