I have a champion (Bannon Heighsley) with command and have him cast it on my spearmen right after my spearmen acted. Instead of my spearmen getting to act, its the champion that gets another action -- and he keeps getting another action. No other character in the battle ever gets a turn.
This bug doesn't happen 100%, but it does happen frequently - forcing me to restart the battle unless I want to take a cheap victory.
