So I have just see a new video regarding the Navcard in tranzit, which is connected to Die Rise.
The player had the Navcard from the tranzit map & it was accepted... Yes I said ACCEPTED, on the Die Rise Navcard table.
He said it didn't do anything at that point in time but I believe it is the next step. He hadn't gone back to the tranzit map to see if it had done anything there but it got me thinking. If the tranzit navcards work on die rise, then theoretically, the die rise navcards should work on the transit map. Maybe if all 4 players swipe their navcards then something might activate or give you a new Navcard or something like that.
