Board Game Arena

I win the game but get much less points than the second one: is it normal?
I got 74 versus 52, but they gave me 18 points and 21 to the second player…

But anyway, if the fist increase because the opponent has resources I don’t have, it is not in the original rules.
Some cards which require 3 stones cost 10 bucks…how it could be?
Seriously something is wrong with maths there

Screen shots are too heavy to attach

Does someone know why do wonders change their cost during the game? It seems happen when the glass is acquired, but sometimes I don’t find the reason. I made some screenshots when the cost is clearly wrong…
