I saved my game after writing down a hash in front of one of the terminals, and when I came back:
I couldn't move. In fact, I couldn't crouch, cycle through my hotbar, or pause. I could right click to edit the paper I had out, but it wouldn't let me exit out of that, either. I then decided to tear off the paper, which not only duplicated the paper for some reason, but it also completely disabled my mouselook and rendered me completely softlocked. The only reason I knew the game didn't freeze was because my food and stamina meters were still ticking down. The weirdest of all? After two restarts of the save, everything was back to normal. I don't know if I'll ever be able to replicate what just happened
