I'm pretty sure it would have been obvious for the characters to figure out that the map they got is being used as a tracker .. but I'm sure the only reason the author isn't making them figure that out is because he wants to use the villain guys to further the plot .. well, "plot" 😂 and it's like the author wasn't really bothered enough to think of another way to make the other guys track them so he just did it like that 😂
Also.. WHO TF TOOK THE CAPYBARA WITH HIM? 😂 I thought they were running away haha .. that damn animal must have been damn smart to be following them lmao
