Saving Changes to Asset Pack - "We are unable to complete your request at this time."

I have received this error upon uploading new images to my asset pack. I have not submitted the pack for approval yet. It seems that altering any of the images will not allow the pack to save.

Any of you have experienced this?

You can save it as a draft, only when it’s published the normal save button will work.

Tried to Submit for Approval, but the same error message pops up.

Somewhat of a work-around, but by changing one picture at a time, saving, and changing another picture, I managed to save and submit all the way through.

Something is still off in the publisher’s portal. The packs just don’t save as they should.
