Nice find, you probably found a bit of the map that is missing the character block to stop you from going off path. Do you know roughly where you went off path.
so that would also mean if I find the right character block I can actually get back on the path. Anyways if you want to find it in the map editor I think it won’t take long, I managed to leave the path on the left, at some point between the very start of the path and the near cabins
