If you take the north exit from the gold 446 you will reveal a permanent event which connects to the cards to the south and east of it, and once dealt with (the direction from which you approach it doesn't matter) will be replaced with 368.
Has anyone sleeved all the cards (black + white + 8 expansions) in thin sleeves (e.g. Mayday 40 microns, 100 per pack)? If so, can you fit them all in the 6 trays? Could you share some pictures?
When you say you "flip a card", do you mean flipping an exploration card as the result of a successful pathfind action? If so, then that is still happening in the consequence step of the pathfind action's resolution, so you would discard after choosing your serenity card.
I'm not sure if you were citing adventure card 71 as working differently from the card you're asking about, but just clarify: for that you would also discard immediately because the only way the card can be revealed is during the consequence step of the action that tells you to take the adventure card, so again the hand limit step will happen right after you pick your card.
