Can't play develpment card. Help!
Yesterday I played mi first game and came across with what I believe to be a bug (maybe I'm wrong): I bought a develpment card and got a Knight, I wanted to play it but found no way to do so. In a quick google search I found that I had to click the card and then click on the "tick" icon on the lower right of the screen (like when you play a road or a town), but this "tick and cross" icons never showed up and couldnt play the Knight card. I tried in different turns and failed as well.
Is this a bug or am I doing something wrong?
You can not use the development card you bought on the same turn.
