Glitched on me twice. After a certain point (Killing Milos, having killed The Worm), it would no longer let me deactivate my weapon at the entrance to the terminal.
Big glitch: I got to the level with the green zombie spawning pools. I took on the 'kill zombies' objective at the start of the day. Only two pools spawned, I'm now stuck on the level. It keeps telling me, "There's something new out there, and you have to figure out how to kill it." when I ask to forfeit the objective and skip the day.
Is there no way to award the game complete badge retrospectively? Because the campaign is REALLY long and I think quite a few of us don't feel like doing it twice just for the badge.
