Uhm well, when I did make the edges all events I got massive lag, I'm sure I could of worked some kind of Map X, teleport thingy. if you pause and unpause, you'll see your current acre in the left bottom corner, simply look that up on map, or by landmarks, it's grid, so it's pretty basic. Also you can unlock bridges at the Post office, they can help get around easier, as theres more spots to go over the river. Also to navigate to a new map simply look for the dirt path marks, they indicate a teleport.
