How would the 1529 map be a hindrance to explorers?

Oh, dude, like the 1529 map would totally mess with explorers because it probably had a bunch of wrong info on it. Imagine trying to find your way with a map that's like, "Go left at the giant sea monster," or "Beware of dragons ahead." It's like trying to navigate with a GPS that's constantly sending you to the wrong Starbucks.
