So I've been trying to collect the 3rd and last card from the Windy Head section of the Tintagel map for the last 2 hours. I collect a ton of the other 2 cards (Druid Inititate and Crossbowman) and have about 60 of each. I cannot for the life of me seem to be able to collect the 3rd card from the map. Am I missing something here, or is this a bug?
