It seems that AS deletes the thumnails/ cover when closing the downloadables dialog (on Amz, not sure about NF) and downloading them again when reopening the dialog. I tried it a few times and after reopening the dialog the thumnails where gone with Loading Artwort... message in place of them. If I'm right, could it be possible to make a cache and only delete the thumnails when closing AS or do it manually? Because there are big seasons and it is not possible to download them in one run. In this case it is better to delete them manually when I'm done with the season. It is mainly a concern on Amz jp, bc I have to use VPN there and sometimes the thumnails are loading for a time. But also on Amz without a VPN.
