Bueno, pues efectivamente no existen esos marcadores. Las reglas son una referencia a una edición anterior. En esta los quitaron y no se acordaron de corregirlo
Esto he encontrado en el foro de BGG.
"Question for Designer: I received game and can't get started because several markers and a board area are missing or explained incorrectly.
Markers: There are supposed to be a Diplomacy 1/2 marker(1.275) and a Game Turn marker (22.11) for the game. They weren't on the punchout boards.
Board: There is supposed to be a Turn Record Track on the board (22.11). Isn't one.
Y el propio diseñador contesta lo siguiente:
"Thanks for the question, John. There is actually no turn record track or marker, and I'm sorry we failed to remove the reference to them. You don't really need to record turns, certainly not beyond the first three. If you decide you want to, you can use any spare marker on the general records track.
That reference to "Diplomacy 1/2" markers is vestigial. There are no such. You only need the 'plunder' ones, which were supplied. Thanks for pointing this out. I apologize for this too. Enjoy the game!"
