For the dev:
There are couple of bugs I've found,
- If you have Theresa coming as nightly routine to your room and then get anyway to her room asking her to come you will trigger twice the scene.
- Finding new rooms can trigger the dialogue "you don't understand the mansion enough" but it will still proceed to the selected room. I did already the mission however perhaps is due I've discovered first the clinic room followed then (when i got this notice) by the laboratory.
