First, I'd like to say that this is a really cool game so far. I enjoyed War of Magic a lot, and I can already see a bunch of improvements over it. One bug I've run into so far is with bows: sometimes (maybe half the time) when I order a ranged unit to attack, the cursor will change as if the unit had acted, but it will not fire. Sometimes it will fire after a minute or two of waiting, and sometimes I have to skip that unit's turn. I don't know if anyone else is having this problem, but I figured since it's a beta I'd mention it in the forums.

Also, I think I saw this addressed in another topic, but it would be nice to have a scroll feature on the tactical battle map - maybe use the arrow keys and/or moving the mouse to the edge of the screen to scroll around, rather than having to click and drag.
