I was quite happy when I was able to get 3 Gold mines all in a row beside my capitol
. Gold mines start out with 2 production and 1 gold yield, but when I work them they are now 2 Gold, 2 Produciton, 4 Hapiness and 1 resource. This seems to be a bug ... at least i hope it is, because the tooltip when you hover over a gold mine states that they will produce 3 Production, 1 Gold, 4 Hapiness and 1 resource.
It's a shame since this such a wonderful starting
