The thumbails for certain packs and collections are no longer provided by the API for a user if the following is done:
-Edit factory thumbnails with viewer user.

This functionality will be hidden later, but a current loose ed on the UI allows to perform this action.

test case:
-user viewer user and go to factory tab
-right click pack/collection and select edit 
-replace thumbnails 
-empty image cache and restart the app
-packs with replaced thumbnails now don't display any thumbnails anymore 

i've performed this action with user Karim1king for a bunch of factory packs, the result is that most packs now display the default thumbnail.

The issue is probably that the app is looking for a local thumbnail which isn't available and displays the default thumbnail as fallback, since the factory thumbnails are now ignored.

the issue is fixed, but it seems that it has introduced another bug.
now it is not possible to edit the images of personal collections.
it works when creating a new collection, but the existing thumbnail can't be replaced using the edit function.

test:

• use viewer user 
• create new collectiion without thumbnail 
• try add a thumbnail with the "edit" function after the creation
