1. Ladders - for some reason assalting forces now pool around 1 ladder rather than climbing up all the ladders - making taking the walls virtually impossible.
A M2TW bug which the version of Darth Mod i included in 2.0 seems to exacerbate. The version of DM which will be in 2.1 does not have this problem as much from what i've seen.

2. some units, cav in particular are behaving strangely sometimes - ie. not responding when given an order (several times), an another instance in a city where my cav shouldve slaughtered the enemies millita to a man, instead they were slaughtered, it was weird - it was like they werent engaging the unit, just running around getting killed.
M2Tw bug.

3. gates - I see what you were doing with the gates, thing is in some recent battles had the AIs army not sat there waiting to break through getting cained by my archers, then they wouldve easily rolled me, which I think would make the game more exciting - that is to say the stacks of troops were awsome, but the flawed AI in combo with the harder gates made them imputent.
Gates in 2.0 are much stornger than intended as i included the wrong file. In 2.1 they will be stronger than in M2Tw but nowhere near as much as in 2.0.

5. I still find the cav walking speed slow when compared to the foot, ie telling the cav to attack a unit single click - when they are a ways off, the cav take ages to get to charge position.
Yeah it does, it seems the move animation is slower, not much i can do about that.

2.1 will hopefully be out sometime today.
