Back cover, but no backcover

In my Movie collection I have the title: Star Trek: Generations

The UI shows that there is a back cover:

But if you click on the back cover it shows nothing:

On the Mobile Android it it shows a broken image.

If I look at the backup XML it shows an url:

<coverbackdefault>https://clzmovies.r.sizr.io/core/covers/lg/bf/bf__1_StarTrekGenerations.jpg</coverbackdefault>
<coverbackfilesizedefault>-1</coverbackfilesizedefault>

But it returns a 403 Forbidden.

Maybe this topic belongs in CLZ Core Errors, not sure if something else is going on. Maybe it just happens sometimes and it is an Core issue instead of a possible bug.

@CLZ_Martin this seems to have a broken cover in Core, I’ve removed it, can you add a right one?

Or feel free to drop the correct back cover here @twazerty
