The Cities and Knights expansion to Settlers of Catan has two cards that have caused us a bit of disagreement.
Take the Mining Progress card for example. It says "...collect two ore for each mountain hex adjacent to one of your cities or settlements." If I only have one settlement and one city and they are both adjacent to the same ore hex, should I collect two cards or four? If you are to count mountain hex then it should be two, but if you are counting cities/settlements it should be four.
The same questions exists for the Irrigation Progress card.
