Every once in a while partway through ground STFs only, my abilities stop working. In the tray I can see the icon register a click for example, but nothing happens. The only thing I'm able to do is move (with wasd & spacebar) and interact with the environment like borg consoles. I can't shoot or do anything else though.
Exactly the same thing has been happening to me the last few days. 3 or 4 times its happened now. Half way through the mission I just stop being able to attack or use items or anything. Frustrating trying to finish the mission just by ordering my away team around.
