Can you put a Door you already opened into Limbo to resolve a Nightmare, and does that affect another Door of the same colour?

Question

Accepted Answer

Yes. That option moves one of your opened Doors to Limbo, and the Door can be obtained again later. It does not move another Door of the same colour from the deck, which stays where it is.
