If you close something and then see it pop up again afterwards as if nothing had happened, that would indeed not be intended. We will look into that for sure. Our apologies for the inconvenience this is causing you.

Edit: If you're experiencing this, you can try to reload the game. It'll most likely resolve the problem. Again, apologies for this rather annoying bug.
