[Solved] Editor problem

I'm currently making a route using a bcakground image I have made from Google Maps. The problem I have is that as I try to move around the editor, it gets to sections where I cannot move onto it, or see my image, or anything for that matter. I can't click any further or create a new tile. Any help would be greatly apprechiated!


EDIT: I've solved the problem, for some reason have got the create new tile feature working again! Sorry for wasting everyones time.
