Sorry to bother, but I was wondering if anyone knew how to fix an issue I have. I just got the new version of Kethane and it was working fine for a while, but now the grid doesnt show when the box is checked. I get a graphical issue it seems with the grid. It kind of flickers as I move the camera around. No errors in the alt+F2 window. Only other addon is latest Mechjeb. Any help woujld be greatly appreciated!
