I'm running UNA 14.0.0 with channel set to Stable.

To be clear, the inability to upload a Persons Cover (PC) appears to have been a cache issue. But the fact that the front-end called my original PC image file in one page but not another? That appears to be a bug, perhaps revealed by the cache? Or a DB entry written by bad data in the cache?

I still have one other profile that is currently in this "split personality" state - with two different Cover images. I can fix it easily, but am leaving it as is in case its useful for further bug squashing.
