“failed to load saved data” error when downloading from the gallery.

This query is on behalf of a friend:

Their lots shared to the gallery, from a particular save file, are yielding a “failed to load saved data” error when either they or others try to download & place them.

For context of the trouble shooting list below One of the problem lots is a rebuild of Municipal Muses with a ghost attached to the lot

The save file is base game only, using James Turner’s pack disabler. BBB, MCCC, UI Cheats, and Larger Households mods have all been enabled in the save as well, and a CAS background replacer. 

Trouble shooting notes:
