Hello,

I have searched high and low for this information and, having not found it anywhere, decided to ask here. I apologize if I missed it in some obvious place!

I would like to know how many sketches are needed for each upgrade level of the resource buildings. In game, it only displays the price of the next upgrade level. I would like to know how many sketches are needed for each level all the way to level 40 for the gold, iron, and food resource buildings. If there is a chart somewhere showing the required amount of sketches for each building that would be very helpful!

Thank you in advance!
