100% GAMEBREAKING BUG! READ THIS, DEVS

[Romulator]

Well, unfortunately, since I personally did not encounter this issue, I am unaware of any solutions as to how to fix it than to go back to a previous save. If that doesn't work, I am unsure what will. However, as a possible workaround, here is my save which takes place just after the airlock.

You will spawn rather shortly inside Tau, where the airlock which you were supposed to enter is directly behind you.

To use it, simply extract the file inside of the .zip into your saves directory. Then when the game has opened up, choose the "Load Game" option and load the save which takes place at Site Tau on 2015-10-13.

In the meantime, I have assigned this thread to jens and raised the priority (hence the green outline around the post in the subforum). He and/or other team members may be able to assist further in trying to fix this issue. I recommend if they ask (their names will be in red, unlike mine which is in purple) for any information, you supply as much as possible!
