Rooms with in-set variants do not render images in deck editor

Title. See [[Unholy Annex // Ritual Chamber]], which I implemented with both of its variants. It has a missing image in the editor:

Compared to [[Bottomless Pool // Locker Room]], which doesn't have any in-set variants. The image appears fine for it.

Note that the images for the lands with variants *are* being downloaded, they just aren't being correctly identified when the card is being rendered in the editor. When playing a game, however, the image does appear when in the user's hand and when on the battlefield with both halves unlocked.
