Hi, My population ticked over from 49,974 to 50,140 but the game will not allow me to buy another improvement, even though I still have improvements that I have not bought. It seems not to be acknowledging that I have achieved the next 1,000 population mark. My nation is at http://www.cybernations.net/nation_drill_d...ation_ID=156856. Thanks!
