Got my first game interfering bug, followed by an (unrelated?) crash.  I will figure out how to post the crash seperately, but the bug was as follows;

As soon as I equipt my champions with horses, then started failing to end turn correctly.  The exact sequence was as follows;

Move the champion toward the enemy, without getting close enough to attack. 

Press the shield button (All three of the champions in this group have both shields and horses.)

At this point, the turn doesn't end like I think it did before they had horses.  So I wait a little while, and then try to press the end turn button.

The cursor is in the mode that shows it isn't active, so pressing the end turn button doesn't work.  Finally I press the space bar, and after a fairly long delay, the unit's turn finally ends.

This seemed to be happening each time.  (Haven't tried not pressing the shield button, that might help.)

This reminds me of the old WOM bug where one of the horse rider animation was taking way too long.  Not sure if that's what's happening here, but it looks like it.
