Edit: See the reply to this comment, it explains the actual reasons behind what was happening in my game
nputting codes into the computer seems to have various effects, I will document this here as I explore. You can get these codes from pausing the game and looking at the monitors in the numpad room. Exiting world when a different password is displayed also seems to have various effects.
Inputting SLQWZ - when you pause, your coordinates show up.
Exiting during SLQWZ - Seems to make the vase spawn in front of the entrance to the keyboard room, Also seems to have a random chance of putting you in a version of the world thats mirrored, has the skybox replaced with solid grey and the work building is missing. There seems to be no way to progress further other than to reset.
Inputting OKOAR - Seems to change the world to its regular mirrored counterpart, also causes a glitched cursor to appear on the pause screen
