Lua Speed Test doors lock behind you, deletes all mission progress and rewards. Bug is a year old at least.

If you turn around and go back the way you came in the Lua Speed test, the doors lock behind you sometimes. There is no way out of the room, you have to quit the mission and lose anything you "earned". 

This bug has previously been posted to the forums several times over the past year, e.g.:

Still not fixed. Very annoyed as I've only found it once so far and it bugged, so no mod for me.
