Hello, During my movement phase, I select the stack. I deselect (right in the window) the units I do not want to move, to keep only the one that will move. I move it, okay. But then I can't select the rest of the stack to move the units that haven't moved yet. Is that normal in the rules or am I doing it wrong?
I tested in game and was able to select a few units from a stack, move them and then select the remaining units left in the original stacking hex and move them as well. One thing you have to make sure of is that you finish movement for the first moved units, until they finish their movement you can't select further units to move, perhaps that is the issue?
