I had an earth shard in vicinity of my city, so I put its earth shrine in my city's construction queue.
While it was in my city's construction queue, I cast Corrupt on the shard. At first the square was blank. When I moved an army onto the square, the death shard graphic appeared. However, the earth shrine was still in my build queue and could not be removed. In addition, I could not queue up a death shrine by pressing the "build" button in the death shard's description pane.
Finally, when the queued up earth shrine was completely built, no shrine appeared, and I still could not build a death shrine on the death shard.
