I am getting an exception with the latest release (0.12.4). On loading a previous craft there is a null pointer exception which seems to be coming from control surfaces. When originally placed they are fine, but when reloaded they no longer are. I've tested this down to a fresh install and only the latest release of the mod itself. Testing was just any pod and any control surface, no other parts attached. cut of output_log: ------------------- initializing editor mode... ------------------ (Filename: C:/BuildAgent/work/ea95e74f6e5f192d/Runtime/ExportGenerated/StandalonePlayer/UnityEngineDebug.cpp Line: 54) editor started (Filename: C:/BuildAgent/work/ea95e74f6e5f192d/Runtime/ExportGenerated/StandalonePlayer/UnityEngineDebug.cpp Line: 54) Untitled Space Craft loaded!
