I didn't, it doens't matter what faction you chose at the lobby you will end up as cybran, just so happnes that the last map i played with sera and that was still in the lobby, it spawned in a cybran ACU anyway

Indeed !
If you look at the screenshot carefuly then you'll see that his ACU is Cybran.

This is a known "bug" that came with FA and I did not fix it up yet.
It makes the UI showing up as if you selected "random faction" so its sticks to that faction's color.

I'm working on that and on the map border setting by the way... slowly.

When i tried playing Solo ACU most of the map was black with the exceptiom of when i am nearly completely zoomed in. Is there any way i can fix this.

I would have posted some pictures but i dont know how to.
