Guide: Crypt Quests

The monsters you need to complete the crypt quests have stayed on after the full moon, but as all of the other monsters have gone its going to take forever to find the flaming skulls. As I already have loads in my inventory, I cant send requests for them, and they keep falling off my wishlist because it is no longer full moon. Does anyone know how long the crypt quests are going to be around for? Is the crypt staying permanently? I think Im going to have to wait for the next full moon to finish this one! If anyone has flaming skulls on their to-gift screen, feel free to add me

Does anyone know if you are fourth in a crypt fight & don't win a chest, do you still get to search the room, or do you lose everything?

If the boss is defeated the crypt opens to everyone who took part.
