Hm. What about installing the lot once, with all the CC, then deleting the lot, and installing it again with the clean installer, but this time only install the lot...?
'Cause it almost sounds like it's somehow doing things in the wrong order, creating the lot before the CC is in place (I don't know if that's even possible, but it's worth a try?).
Edit:
The same is true for the lot that was already placed in the 'hood when I switched computers--even with all the CC in the proper folder, the lot is completely stripped.
Of course, my theory didn't take this into account.
Very strange. :/
Try it in an otherwise CC free game too, just in case?
