I got through the assignment history at the start but wanted to do a different assignment. When I reloaded and chose a new assignment, the transition cutscene played, I got the stat bonus, the next cutscene played, and I was stuck in the shuttle bay where I just was. This persisted even after reloading and when I tried to start a whole new game. I couldn't even get past the tutorial area. What the hell?!

reinstalling the game would be a good start. also, windows or mac?
