I had the same problem.
1. Go into lunar magic and open overworld editor
2. Click the Hill with a star on it (Layer 2 Event selector)
3. Hit the page up button untill all 77 events are highlighted
5.Use the 16x16 tiles to make you overwotld pathes
(Remember to set the levels to activate the correct evnets when they are beaten!)
I hope this did not confuse you to much
