Hi there,
Just a minor quality of life issue: Can we get a confirmation yes/no popup when a hero is leaving an army? Often times I will have a hero selected because I have just upgraded their skills and I think I have the army selected afterwards. When I click to move the entire army, instead my hero separates from the army and it takes a whole turn to get him back in. A simple confirmation popup would solve this annoying issue.
I could also pay more attention

but when you're conquering the Old World it's easy to get distracted. Thanks for my favorite game of all time!
