I noticed this months ago and reported it to CS. They asked me to do it again to provide screenshots. After I did that, they replied that it was a known issue they were working on. I asked why, if it was a known issue, they made me do it again to provide screenshots knowing that it would cause me to lose crowns, and whether they would refund me the crowns I've lost due to the bug. They said they would not refund crowns until they have the bug fixed.
Like I said, that was months ago.
