Recently bought DA and i'm playing the 2nd campaign mission right now. I am at war with the Korx, Humans and Altarians and the Korath are my allies.

Problem is, i have invaded a human planet but i can't seem to invade other planets. They have no ships in orbit but my colony ships don't invade. I have the ship selected and adjacent to the planet and when i click on it, the ships updates its destination with the planet name, but it doesn't invade even if it is right next to it. This happened with the last human planet and with other korx planets. Is this a bug?

One other thing i noticed is that whenever i attack a korx mining field, my ships lose all movement. For instance, at the beginning of the turn, my fleet has 6/6 movement. After i attack the mining field, i get 0/1 movement. Even if the korx had the Super Isolationist hability, this behavior is very different. Did anyone have this experience?
