Mods installed: Chatterer v0.9.5 EnhancedNavBall v1.3.6 HullCameraVDS v0.4 KerbalEngineer v1.0.17.0 RCSBuildAid v0.7.2 Third attempt: I get my ship into orbit, and begin to execute maneuvers to close with my target, at some point while planning a maneuver in map mode i will hear an explosion and one of my structural fuselages has randomly exploded. There was no vibration or indication there was any undue stress. This has happened as early as 30 minutes into the flight and 10 hours into flight. The output_log.txt file simply reports: Is there maybe something wrong with how I built the ship? I am fairly new at this game. Below are some screen caps of my ship and after it blew. I circled the part which blows up. Any advice would be great.
