Are there only 3 of each? They seem rather crowded around the center of the map, so I'm assuming I've missed some.
These are the ones I know of, please reply with any I might have missed:
Machine Room in Canary Send, Besara
Machine Room in Middle Valley Clearing, Groddle Forest
Machine Room in Otterlane, Groddle Meadow
Bureau in Chego Chase, Andra
Bureau in Baeli Bray, Muffo
Bureau in Gregarious Grange, Groddle Meadow
Thanks in advance for any help.
