I often have 4 or 5 generals in motion at a time. This is no longer safe as any general returning to barracks or recently sent to attack or transfer can replace the window of the currently selected general. This interferes with the sending of generals and the addition of troops to a general.
In playing a simple adventure (Ali Baba and the Second Thief) I had the following problems:
Whilst adding troops to a general the window kept resetting to another general's.
When sending a general a different general was sent to the attack.
When clicking on a sent general a different general's window was displayed - making it impossible to order the general to retreat. (not sure what triggered this behaviour).
This makes adventures very tedious and frustrating to play.
