I believe that the bug here is that the access card you can get from the hacked terminal on level 2 is actually just a keycard to a second entrance onto the third floor (reached by climbing the rubble and going through a door on level two). I think the access card was intended to grant you permission to be on the third floor like all the other floors' access cards but for some reason it doesn't work that way.
I have found solutions to this problem but they are not ideal with the way I like to play the game. I would have liked to have obtained permission to be on that floor and not have to disable or fight the robots once I am there.
Has anyone else encountered this problem?
