I have some art uploading for my game (4732, 3rd deck) but it's got stuck most of the way through.

I can't delete the deck and start again because it says there is art being processed... but the progress hasn't moved in 30 minutes.

I managed to get round it by uploading the files again anyway. The old ones still say they are "processing" though, don't know if that will mess things up in the future.
