I'm potentially about to run the Temple of the Six-Limbed Lord adventure site by Zedeck Siew, which is part of the "Crypt of the Mellified Mage" adventure site pack.
When looking over the map, I see that there are 7 locations across the map, and they're numbered as such (1, 2, 3, 4, 5, 6, 7). However, on the western wall, another location is numbered "13". This looks potentially like a crack of some sort in the wall, but I'm unsure. There is no mention of a location "13" (much less any 8-12) in the adventure module.
Anyone have any guesses as to what's up with this? Is this a mistake left over from an older version?
