idk if it a bug or not, but I keep finding the game is giving ZERO gold in the gold mine. Only 300 every so often from the throne room...
I upgraded them mine to level 3 and still nothing. But I also noticed you are correct. Other squares DO produce gold. So by the data, seems to be both my error (as I was on a square that slashed gold production) AND an error, (as the square oly impeded production and shouldnt have cut it off completely. Thx for the info tho! ^_^
