On page 11, in te description for area A2, the text states that a trap “triggers the first time a PC steps on one of the marked squares”, but on the map, it does not appear that any squares are marked as far as I can tell. Is there any clarification available?
I came to the thread looking for the same information as you. Roll20 has maps of the book for free so I referenced how they had set up the official maps. The marked trap triggers are NOT present on the map, but are located in A2, one a square or two at each end in the center row of tiles. It looks to be an error with the marked squares not being printed. I think it's confusing because A2 on the map looks more like a control room.
They are also not the A3 traps, as those are spread between the two zones of A3 (four squares in total) and those ARE marked.
I would agree with TheCaptin above, though, to say the elevator is intended to be the area beneath A2, but on Roll20 they mark it in a random spot close to A1.
Hopefully an official response can come along and clarify those for us.
