I installed Project Orion 3k Extended Boundary, I installed all the other mods that are said to be need - located on the page. The Extended boundary seems to be working fine, I can see that it is bigger, however I can't seem to build any roads or put anything else past the original boundary. When I drag a road to place, it just stops at the old boundary line and won't go any further. Does anyone know if maybe I am missing a certain mod to fix this?
