So, basically I found a treasure map for the achievement and I went to go find it and found myself in the middle of a forest. Now from what I know these are supposed to be on the shore's. And with the nearest water source (being a river) about a hundred blocks away, and the nearest ocean maybe a few hundred. This is most likely a bug! Now I know this getting fixed won't this specific one. But it might help people in the future. Thank you
