In the second mission: Restoration, there is a bug that forced me to go back into orbit and restart the mission. When I got the objective to "Access Cosmodrome Network" and I deployed the ghost, I walked into the sewer and pressed the button that causes the ghost to show up in your hand. When I did that, the game kept asking me to deploy the ghost at the computer, but the ghost is already there and doing nothing. I then had to go back into orbit and restart the mission. If anyone else has a bug similar to this in a mission, please post it.
