I went to the Rooms overlay to see if my Medical bay took, and I noticed an unusual amount of the Latrine's blue.
All of the Mesh/Airflow tiles (including some out of the base to the left) and Pneumatic doors (plus half of two Mechanized Airlocks at the top) are appearing as the same room (they all light up when moused over). Latrine still gives the buff as normal, and is reporting as normal.
I had opened the Room Overlay after fixing a Med Bay and noticed this behavior. I'm unsure if the Med Bay had anything to do with it, but I didn't open the overlay until after fixing it.
