I've been having this bug for over a week now. I order 30 balloons in the barracks, there are enough resources, there are enough people. I press train and it starts to train not 30 balloons, but, for example, 12.
I order 12 mortars, start building 1 mortar, I order 6 mortars - 1 mortar is being built
The same is true for other units. I now have 3 orders in the barracks for 1 mortar. You have to wait and order again to get the required amount.
Also, after updating with large dry cargo ships from android, gold, the economy section with gold costs, and the amount of gold are not displayed. A window with a large cargo ship threw out a window with gold. It's less convenient to play on the phone
