This question came up during a session yesterday. The hunters did their actions during the day and night. Then during dusk and dawn they sometimes played event cards that said to play during dusk or dawn. It became kind of like an extra action.
Was this correct? If not, when are you allowed to play these cards?y
Sounds you were perfectly correct. Cards that say you play them at Dawn or Dusk mean exactly that, they can't be played at any other time.
It is probably a good idea to ask at these times if anyone has any cards to play to avoid people missing the chance by having moved on too quickly.
