Photos/Paintings turning black/blank (1.102.190/1.82)

Oh dear. This was an issue previously—usually when storing pictures in the keepsake box, or, before that, randomly. It sounds like you’ve done what I did to fix it: rolled back to a previous version of the save. 

Have you tried saving pictures to a library/gallery room and seeing if that helps, or if they’re affected as well? My pictures and paintings from reference were safe in my library, fwiw, although obviously you don’t want to replace them whenever you load the save! But perhaps you would only have to replace them once? 

(Try it as a “save as.”)
