I see the same issue: from a game ending, clicking on “Play Again” takes you to the game’s page but the restriction settings (behind the “door”) are all default. If I reload the page, the restriction settings come up the way I had them configured before. (I almost never use that button so hadn’t seen this problem before now.)
Have you filed a bug? Because it won’t be fixed if nobody at BGA knows about it… in the meantime, just remember to reload the page after clicking “Play Again”. Not ideal, but I don’t have anything better.
