Why is resource production so low in second city?

[arthurv]

I recently conquered a second city and when I leveled the Quarry/Lumbermill/Iron mine to level 20 I have noticed that the production is well behind my first/main city at the same level of building. The difference seems pretty substantial (like 1032 vs 1376 at level 18) as a concrete example.

I thought that the resources generated were fixed on a world basis - is there a city by city difference? And if so what can be done to increase the production?

1032 is production for a level 18 building. 1369 is production for a level 20 building.

You likely have a refresh issue. Try restarting the application and looking at your numbers, ensuring that each city is refreshed and has pulled the correct data from the servers.
