So i am trying to make some gangzones but the problem is that when i get close to the edge of them they .. 'move' i could say ?
So here are some screenshots to see exactly what i mean..
How the gangzone needs to be and it is when i'm inside it:http://i.imgur.com/d9dSv.png
What the gangzone does when i am at the edge of it:http://i.imgur.com/KIoMH.png

Is there any solution to this ?
