I recently purchased KSPon my XBox One. I have been playing off-and-on on PC for a long time. I cannot place maneuver nodes.
In preparation for the inevitable responses, let me clarify: I have upgraded everything several times as my inability to place maneuver nodes started in-game. So, that's not the problem. I have reloaded and still can't do it. I started a new game completely and that also didn't work. I can't even place maneuver nodes in Sandbox mode or the training levels.
I hope someone can help me out.
Thanks, Jon.
