I've done all my reviews for the day (0 left to review), yet there's a white block. It wasn't there when I finished the reviews earlier today, but it appeared a bit later out of nowhere. I was thinking it might be related to the new holiday system, but I don't have that system enabled (and never have).
It would be really irritating if I got a white holiday block there, since I've been looking forward to filling up the entire year with dark blue blocks.
