In the rules it states pay 1 coin for each technology but on the scenario board it shows to pay 2 coins for one technology.
Which is it supposed to be?
I believe this is most likely a failure of the choice of image for the money on that event. Thus it's most likely 1 coin as per the rules. However, it is ambiguous and the error could very easily go the other way. Clarification from the designer would be appreciated
