Decks created with assetbundle as face/back imports entire sheet as individual cards#2130

When importing a custom deck using an assetbundle as one of the card images, rather than splitting up the image as expected, it instead imports the entire sheet as the face for every card in the deck. An example of the behaviour can be seen in the attached image.

Additionally, single cards imported with an assetbundle as a face do not seem to properly hide their faces from other players when placed into a hand.
