Im playing KSP often, and I like playing with mods, but every time I try to recover my Vessel or to go to Space Center, nothing happens. The button get's pressed down, and then goes up again as usual, but nothing happens! I know this is because of the NullReferenceException thingy, but I don't know how I can find out that is causing it in the output_log.txt! Here is a copy of the "forever" repeating message: NullReferenceException: Object reference not set to an instance of an object at ConfigNode.CopyToRecursive (.ConfigNode node) [0x00000] in <filename unknown>:0 at ConfigNode.CopyToRecursive (.ConfigNode node) [0x00000] in <filename unknown>:0 at ConfigNode.CopyToRecursive (.ConfigNode node) [0x00000] in <filename unknown>:0 at ConfigNode.CopyTo (.ConfigNode node) [0x00000] in <filename unknown>:0 at ProtoScenarioModule.Save (.ConfigNode node) [0x00000] in <filename unknown>:0 at Game.Save (.ConfigNode rootNode) [0x00000] in <filename unknown>:0 at GamePersistence.SaveGame (.Game game, System.String saveFileName, System.String saveFolder, SaveMode saveMode) [0x00000] in <filename unknown>:0 at GamePersistence.SaveGame (System.String saveFileName, System.String saveFolder, SaveMode saveMode) [0x00000] in <filename unknown>:0 at VesselRecovery.onVesselRecoveryRequested (.Vessel v) [0x00000] in <filename unknown>:0 at EventData`1[Vessel].Fire (.Vessel data) [0x00000] in <filename unknown>:0 at VesselRecoveryButton.recoverVessel () [0x00000] in <filename unknown>:0 at ScreenSafeUIButton.OnMouseUp (Boolean rightClick) [0x00000] in <filename unknown>:0 at ScreenSafeUIButton.OnMouseUp () [0x00000] in <filename unknown>:0 at SSUICamera.DoMouseEvents () [0x00000] in <filename unknown>:0 at SSUICamera.Update () [0x00000] in <filename unknown>:0 ​I know there is supposed to say which file that is causing it, but I can't see it in here! Please help me with this! It happens all the time! Everytime I complete a mission in Career mod, and collect alot of important science, I can't recover it! It's driving me CrAaAaAaZy!
