Thanks for all the advice everyone :) I will talk to the leader, but he is currently on holidays and cannot do anything. I appreciate all of the help and advice :)
I am a little confused. I have upgraded my cob gen from coal to iron to gold but after at least two or so weeks (therefore multiple logins) it is still not producing anything other than coal and stone. Do I need to do something special to get iron and gold? Makes me not want to buy the diamond...
