Havn't encoutered as many CTD as you chuchskull but the few times it did happen it's really annoying as you don't know when the last auto save is
I did have a CTD every time i hit end turn on about turn 12 which i got through by pressing space bar and having the cpu moves done slowly. (it took a few minutes to watch it all though)
Havn't encountered the disembark bug though, it's been fine all the time's i've used it although it's different from previous games where you would get the disembark order when selecting a move order for the ships, where as now you have to take the ship close, select the army and then disembark. The change seems rather odd and was much more fluid before.
For some reason though the artillery limber/unlimber is bugged with certain guns on my game. The horse drawn guns all unlimber themselves as soon as they've limbered up and there's nothing that can be done. Also the 24lb foot howitzer has the same issue so i tend to just go with the 12lb foot cannon as it doesn't seem to be bugged if i want to move them in battle.
Some of the cannons have trouble stopping firing aswell, you tell them to stop and they just start firing again. I can tell them to fire at ground and then tell them to stop but if the're firing at a unit they won't take the order.
Still probably the most adictive game i've ever played but hoping they'll get fixed soon.
