Merchant bug with resource depletion
Merchant card cannot be placed on a resource hex without a number token in the resource depletion C&K scenario. There is nothing in the card text that says a number token would need to be on the hex to be able to place the merchant.
I have recently played a game and could not place the Merchant on wheat after playing Irrigation. Only fields with number tokens were possible Merchant placements. I think this does not reflect the game rules and should be corrected.
