I have been playing a new game since 1.04 released. I have had the CTD that occurs after playing for several hours, but no other issues until today. Now, I’m having a game breaking issue that I’m not even sure how to begin to troubleshoot. Hope some of you have some suggestions This afternoon I started having a strange visual bug. In the VAB and SPH parts started puffing smoke effects as if they were engines constantly shifting from full throttle to off and back. If it is an engine part, then they have full throttle animation with exhaust graphics. Additionally, all staging displays disappeared. Shifting to the Launchpad caused the problem to cease and staging could be adjusted. But reverting to the VAB renewed the issue. In the debug menu I get this exception whenever I add a part: [Exception]: XmlException: Document element did not appear. file:///C:/Users/Ed/Desktop/KSP 1.03/Kerbal Space Program/GameData/TweakScale/plugins/PluginData/Scale/config.xml Line 1, position 1. Anyone have any ideas?
