2 Bugs, 2 possible bugs:
1) Mentioned earlier, not sure if a response was given but when telling your men to brace polearms, they brace them and are stuck that way, despite "cancel order" and other commands given to them. I tested this by taking all of my polearm troops out, deploying them, and trying every command in a battle against some random looters.
2) When a turncoat declares and takes his city with him, I asked good the good old Doge to attack it. He went to siege, did his thing, and then moved in to do battle. Except he froze there, stuck in between siege and a fight. I was unable to click on him or interact with him. He stayed that way for 20 days when the city simply fell from starvation.
3) When fighting vastly outnumbered garrisons and meeting with a commander, not once have they tried to seek terms so I slaughter them. Is this something I must do after starving them for awhile?
4) When Marshall, I command about 500 troops and move into relieve a siege of about 200 attacked. None of the men with me join when I attacked and, upon approaching an equally sized force, they flee in random directions rather than following.
