I'll just paste what I posted at the official forums a while ago
Bugs
- There seems to be some memory leaks in the game. It usually runs fine but sometimes during a battle the framerate will plummet and remain choppy on the campaign map afterwards. Only fix is to restart the game.
- Units produce dust during rain storms. Idle horses left behind by dismounted dragoons will produce dust like they're walking. Also, if an artillery crew is fleeing, their artillery left behind will produce dust.
- Moscow Musketeers can't be recruited in the campaign.
- DLC units do not appear in multiplayer campaigns at all. I suspect that this is a conscious decision (for some reason), but just in case I thought I'd bring it up.
- Difficulty sliders in multiplayer campaign set-up flicker back and forth and make constant clicking noises.
- Part of the text on mouse-over information bubbles is cut off in battles.
- Artillery units target the flanks of units instead of the center, causing them to totally miss most of the time.
- Historical battle maps available in multiplayer but not in custom battle.
AI issues and critiques:
- Battle AI can't handle fire and advance well which causes massive problems. Battle AI sometimes risks it's general in very stupid ways
- AI Britain rarely does anything in any campaign I've played and it's been confirmed by many other players. They also usually lose the sea war with France.
- AI Spain never does anything either, including never attacking Gibraltar...unless Britain is controlled by the player.
- Portugal too resistant to alliance with British, locking out a chance to roleplay the campaign historically.
- AI allies refuse to accept free territory unless something (i.e. anything) else is offered with it, like any random tech or 7 pieces of gold.
- Battle AI use of cavalry not as good as in ETW. Instead of going on wide flanking maneuvers and threatening your artillery or your rear, they usually just charge straight into the firing arc of your infantry and get vaporized in seconds.
General critiques:
- Russia immune to cold attrition, but Sweden not?
- Line infantry can still form squares after being engaged in melee. The people who went to the community events reported otherwise. Why was this changed?
- Ottoman starting army is very weak and open to speedy conquest by Russia, even on VH. Starting buildings also a problem, since if you leave them alone they only produce low quality peasant levy type units, which really only serve to give Russian units some extra chevrons on their way to Istanbul and Athens.
