Okay, so I found out what happened to all the .Sims3packs. The EA launcher, and the game itself, no longer correctly reads them. Anyone, most noteably TSR, who relies on them, is now fucked. A workaround exists, but it involves DARK SORCERY and ELDRITCH ABOMINATIONS, so that's right out for TSR. But I fixed it.
:ROFL: After all the pain .package supporters (mainly MTS) went through, and many creators jumping ship to use the .sims3packs this is at least a bit of poetic justice.
