Defensive measures is glitching out and not letting me pass the mission. The shield will go from green to red like it is supposed to do and then the builder tries to get it up and running while I survive. I have survived for over 10 minutes with nothing happening. I have watched videos and know that this part isn't that long at all. And all of my auto saves are now this mission and my most recent manual save is 4 hours behind my progress. I feel like I have wasted £50 on a game that is over a year old and should definately not have glitches
