In game #150708903 on GAMESERVER_NAME (<--- perhaps another bug?) I topdeck a Tanooki with Pilgrim. I then draw it into my next hand. During my opponent's turn, it still appears visually to me that I have a Tanooki on top of my deck (I'm unsure if I would actually be able to do anything with it if my opponent did something like force me to draw a card, but it looks like it's there). By my turn, the graphic interface is correct.
What animation speed are you using? That seems to sometimes influence certain display bugs.
I could not reproduce it when loading the game, but I don't doubt it happened.
