After recovering from a crash caused by opening "Images of the Saints" (reported elsewhere), I ran Logos again and opened the resource again. I waited a sufficient amount of time for all the thumbnails to populate, but some of them never did. I can hover over them and see the identification of the saint, and I can click on the little square and it will open a large image of that saint. But the thumbnails of some saints are simply not there. Could it be that the crash I experienced interrupted the loading/caching of the thumbnails in a semi-permanent way? Is there any way I can clear some cache and get the thumbnails loaded afresh?
Log file attached.
Notice several missing thumbnails that just show up as little squares:

When I hover over one, it does identify the saint:
