Hello,
After log in, the economy overview will show you the wrong information about the productions, but it will correct itself after an hour. It looks like that if you log in, the economy overview will show you only the data of the productions, counting from the log in and not for an hour.
And if you buff an vertical production line (example: foresters - cutter - sawmill), and than see detailed production data of a cutter in the economy view, it shows only the extra production of the cutter and not the sawmill, Example: Cutter 2K + 2k / Sawmill 2k. When you go to the sawmill, you see: sawmill 2k + 1k. It looks like that the (detailed) economy view will show the buffs of one production instead of both (only the cutter) and 'forget' the buffs of the other (sawmill).
Helpful?
