Further testing and this only happens in career mode works fine in any other mode so I'm guessing it has to be setup with other parts? I have tried many different combos even a full base but still same thing happens. this was in the log: [EXC 12:05:08.196] NullReferenceException: Object reference not set to an instance of an object ScienceAlert.ScienceAlertProfileManager.OnVesselCreate (.Vessel newVessel) EventData`1[Vessel].Fire (.Vessel data) Vessel.Initialize (Boolean fromShipAssembly) ExLP.ExBuildControl.getBuildCost (.ConfigNode craft) ExLP.ExBuildControl.LoadCraft (System.String filename, System.String flagname) ExLP.ExBuildWindow.craftSelectComplete (System.String filename, System.String flagname) CraftBrowser.drawList (Int32 id) UnityEngine.GUI.CallWindowDelegate (UnityEngine.WindowFunction func, Int32 id, UnityEngine.GUISkin _skin, Int32 forceRect, Single width, Single height, UnityEngine.GUIStyle style) Well many edits later and it was science alert that was causing it lol.
