Playing the first mission, and found I had just joined up with Darlan and defeated the main wave of Xenos. I got the dialog about beating the main wave then had the cut to the northern lock being jammed open, got the animation of the Xenos coming through. To my surprise, it looped back to the dialog about beating the main wave, then the same dialog about the lock and the animation of the Xenos coming through.
After that, I headed north, and got the dialog about the initial airlock blowing up and bulkheads closing (for the second time). Then I got the primary objective to go help Darlan
I moved a few more squares and got another repeat of the initial airlock again.
