Some of my (random) trello covers are faded. I do not have any power-ups installed so it's not the Aging Power-Up. I tried deleting then re-doing the cover which worked, but then would randomly fade again even if it's a card that was used recently. Some of my covers are fine, even if I have not used them as frequently. I'm puzzled. Attached are screenshots. I'm sure there's a simple explanation, can you help me out?
