My issues started after updating from 1.5.7, no thumbnails/pictures would load characters, troops, inventory, vendors, etc. maybe 1 or 2 out of 100. Made a large stash in Myzea a few hours before the crash. Crashed after completing the "Disrupting Supply Lines" main quest upon defeating the caravan. Returned an hour or two later to Myzea and the stash was gone. However, after the crash, my thumbnail/pic issues were resolved.
