Sorry, Lunie, got distracted.
It's in the Downloads folder, (still in Quarantine). The CEP file is loose under Downloads, so I think the Quarantine folder contents would be loading after it.
I'll try the rug fixes on their own just to make sure.
Oh, and I downloaded the mixed-EPs set, because I don't have all the stuffpacks.
EDIT - still the same. I left just your

package in the Downloads, the other part of your file should be still in the Bins. Then I
loaded Strangetown and tested a couple of rugs in the Specter house. The rugs looked fine indoors - off-grid and diagonal, live and buy mode. On the paving outside, though, the same as before - it was outside that I tried them the first time too.
Hopefully, here's a picture:
