When expanding my exploration of the map, two tiles seem to be incorrectly still 'unknown' surrounded by revealed tiles.
If it matters, my dupes thus far have not actually gone into that area (obviously), nor to the area on the left. Home printing pod is roughly, um, 3-4 'rooms' (4 tiles high) above what is being constructed in the upper right almost directly north of the geyser

my digging path was pretty circuitous around this area - dug a semi-long ladder to the right about 10 tiles off screen down to this area.
