A couple weeks ago, my covers stopped populating in my YACReaderLibrary cover flow. The comics are there and if I open them I can read them fine. The covers just don't preview. If I mainly go in and select a different page as the cover, then back to the original, it will then show up, but I can't do that for the hundreds of comics I have. For what it's worth, I store my comics on a network drive. I'm using YAC version 8 and Windows 10. I've attached my logs.
But here you are saying that forcing the recreation of the cover works. In your library there should be a folder called ".yacreaderlibrary" and, inside it, a folder "covers", you should be able to see there all the covers of your comics, if not, you have to recreate your library (deleting it, and then importing it again).
