Overview of the bug: I make a trade using the administrator window. I have the capicity to trade 5000 units of resources. I trade 5000 so it says I have 0 units to trade, as expected. During the trade it says I have 0 units to trade, also as expected. After the trade completes it *still* says I have 0 units to trade (but it will still allow me to trade 5000 units so it is a display bug). Refreshing the trade tab or closing/opening the admininistrator do not show the correct value of what a city can trade.
How often this occurs: On every trade
Work Around: Logging out and logging in is the only workaround. Of course, that is not at all convenient when trying to use the manager to manage resources between your cities!
