I'm not sure if this is strictly a bug, but its pretty problematic.
A. When I click on things, like forest. Sometimes I get the move command instead of the harvest command. The exact spot to click on being kinda tricky sometimes.
B. When I clicked on a enemy to tell my battle mage guy to fight it, I guess I had actually clicked on the terrain. So the game told the unit to go there instead. But then the enemy I told it to fight was on that space or moved there or what ever. So my guy wandered around the enemy unit trying to reach that space, that all the while the enemy was striking it. It of course died quick enough without landing a single blow.
