I found a Dragoons bug in the battle map. Whilst playing as GB, fighting a dirty pirate mob, I had my dragoons dismounted to get a few volleys of and then told them to mount up for a withdraw and charge. However, a couple of the dragoons got caught in the open (literally less than five men) before they managed to mount up and entered melee combat. The problem is that the rest of the platoon just sat there on their horses and did nothing. I couldn't move them, I couldn't dismount them, I couldn't do anything with them - they just sat on their horses and watched their mates die... then continued to sit there.
