Bug in main mission "One flew over"

spoilers

#1

I did not see the first key card by the computer, so I went out exploring. For some reason the meat warehouse was open, so I entered and killed everything. I managed to open the cell door, but the cell was empty. When I finally found the key card and came back, the cell was still empty. Could not trigger anything from the computer. So I had to reset by reentering night mode.
