I know that disappearing crowns has been a common glitch, but this recently happened to me and I see a very simple pattern. I was in a coop battle with my brother and we won. He had 80 something crowns and then after winning the battle he had 129 crowns. I had 600 crowns and when i won the battle I ALSO had 129 crowns. So I'm assuming there is some value error where it accidentally sends me the same data it sends him? This occurred after I seiged Ral Nistro, which should be seen in my logs. One last note, the patch logs said that players getting the wrong amount of crowns after sieges was fixed? I don't know if this was actually fixed unless I got a different glitch.
