Main deck image doesn't change properly with printing updates

[Kerakis]

Steps to replicate:

1. Create a deck and add any card that has more than one printing other than a basic land.
2. The main image will become the artwork of that card.
3. Swap the printing of the card to something else.
4. Click "Change card image" on the deck header.
5. Choose the added card, which should display the current artwork and press save.

Expected result: Updated main image to the new artwork.

Actual result: The main image in the deck header disappears entirely. Refreshing the page results in reverting to the old main image.
