[SPOILER] "Stuck" in centrifuge level

[Integria]

You'll probably need to load an earlier save. I got locked up for good in the centrifuge, the following way.

1) Went to the upstairs portion, neglected to put the tube in the vacuum... thing.
2) Jumped down, back to the centrifuge
3) Went into the cooling area, got the tube, triggered the shift in layout.
4) Trying to go back to the area with the first tube at this point is impossible. Both doors are permanently closed.

Edit; didn't notice the last part. Good thinking with the chair. I'm still quite confident that it is an unintended bug, though.
