Not sure if this is unique to the new version or not. Anyways:

I started playing thru the skirmishes, beat the first three. After each one, I just clicked "Play Next" and moved onto the next one.
For some reason, when you move on with "Play Next," after beating it the game gives you a score of zero and doesn't show the star next to the name of the scenario in the list, signifying that you did beat it.

So, basically I played and beat three scenarios and it says I only beat one of them.

I'm sure someone could circumvent this by hitting exit each time and selecting from the list, but I thought I'd just bring this to the devs' attention anyways.

yes it is a bug.the system of "singleplayer score points" was introduced in last patch only and all this system is a one whole BUG.So dont pay attention to those points they are not so hugely important - if you did won the scenario it is okay.

thanx for posting this bug,
we will fix it.
