Mismatch between resource production and 'inner' storage
There seems to be a big mismatch between timber/bronze production rates and the 'inner' storage of those resource buildings.
The internal storage capacity for timber & bronze production buildings for levels 22 to 24 inc is 6650 (I cannot remember what it was for 20 & 21). So, this means that - even if you do a last minute transfer to your warehouse - then the the inner storage is full before even a short-ish night's sleep is over.
This was not the case for the original levels up to 20.
I know Plarium want us to log on as often as possible. However, considering how much you have to spend on Upgrade Sketches in order to get the production buildings up to the higher levels, it is grossly unfair to find the production is compromised by the small storage capacity that does not match the production rate.
A bit of fair play here would be nice.
