KSP Version: v1.04 latest verison on steam. Using Windows 7 64bit. What Happens: Maneuver Nodes Disappearing After Encounter Calculation Mods / Add-Ons: All Stock Playtime: I've played for 55 hours, and have at least a decent understanding of how things work. I've landed on Minmus and the mun and returned safely, in addition to other orbital maneuvers. Steps to Replicate: 1) Build any craft that can encounter another body (like the mun, minmus). 2) When setting up a gravitational capture by another body, after the node is configured to have an 'encounter' (brown and purple coloring the node), after the input it seems I can't create further nodes. Anywhere I click to create a node does not seem to work. Result: Can't create new maneuver nodes. Fixes/Workarounds: - I save right after I setup my encounter maneuver. Then I reload that immediate quick save and it seems to reset the ability to create maneuver nodes. Smiles
