I have gone through all of your threads on how to fix this issue (thumbnails not appearing randomly throughout my gallery) and none have worked.
The strange thing is that at first it was only images I recently loaded. Now, after all the "fixes", thumbnails that were once working fine, don't work anymore.
Can someone please, please, please help me before my client kills me?
Here is an example of one of the broken thumbnails:
