Hello, can somebody please help me? I'm getting some sort of bug with SXT, here are the steps that led to it: (each step was done with CKAN) 1 - Completely fresh installation of KSP - Works fine 2 - Installed mods: Realism overhaul and all dependencies (but no extra/recommended mods) - Works fine 3 - Install SXT - Contracts disappear, NullReferenceException pops up in player.log(see below), game ui completely nonfunctional after i enter the contract building. 4 - Removed SXT - works fine again 5 - Installed SXT + Firespitter + RP-0 - Broken again Here's the NullReferenceException: NullReferenceException: Object reference not set to an instance of an object at Contracts.Contract.Save (.ConfigNode node) [0x00000] in <filename unknown>:0 at Contracts.ContractSystem.OnSave (.ConfigNode gameNode) [0x00000] in <filename unknown>:0 at ScenarioModule.Save (.ConfigNode node) [0x00000] in <filename unknown>:0 at ProtoScenarioModule..ctor (.ScenarioModule module) [0x00000] in <filename unknown>:0 at ScenarioRunner.GetUpdatedProtoModules () [0x00000] in <filename unknown>:0 at Game.Updated () [0x00000] in <filename unknown>:0 at GamePersistence.SaveGame (System.String saveFileName, System.String saveFolder, SaveMode saveMode) [0x00000] in <filename unknown>:0 at MCSceneSpawner.onMCDespawn () [0x00000] in <filename unknown>:0 at EventVoid.Fire () [0x00000] in <filename unknown>:0 at MCDespawner.BtnExit (.POINTER_INFO& ptr) [0x00000] in <filename unknown>:0 at (wrapper delegate-invoke) EZInputDelegate:invoke_void__this___POINTER_INFO& (POINTER_INFO&) at UIButton.OnInput (.POINTER_INFO& ptr) [0x00000] in <filename unknown>:0 at AutoSpriteControlBase.OnInput (POINTER_INFO ptr) [0x00000] in <filename unknown>:0 at UIManager.DispatchHelper (.POINTER_INFO& curPtr, Int32 camIndex) [0x00000] in <filename unknown>:0 at UIManager.DispatchInput () [0x00000] in <filename unknown>:0 at UIManager.Update () [0x00000] in <filename unknown>:0 at UIManager.DidAnyPointerHitUI () [0x00000] in <filename unknown>:0 at SpaceCenterCamera2.InputCamera () [0x00000] in <filename unknown>:0 at SpaceCenterCamera2.Update () [0x00000] in <filename unknown>:0 The player.log looks fine until that point, no errors, no exceptions, no warnings. Am I missing some required file? Thanks in advance!! Edit: Oh, I forgot to mention I'm playing KSP in 64bits under Linux. EDIT 2: Now the game doesn't even load anymore, crashes while loading SXT parts According to system monitor KSP uses less than 50% of my memory at the moment of the crash.
