Do you remember which room it was? I have a really janky system for "hiding" rooms (that's why you can see enemies in them), so I'm not surprised it happened, but I can't reproduce this bug on my machine, I was testing it a lot :P
Um, not sure, it was like below a big room with weird dog cages, an assault rifle at the top and I think a keycard? It was an L shaped room I think? There was also a smaller very tight room in between those
