I'm having a number of strange issues. I have the following mods installed: Kethane Extraplanetary Launchpads Sphere Launchpad HyperEdit Sometimes in the VAB, I'll try to put a Kethane part on a vessel and nothing will happen, and afterwards I will be unable to put ANY part on the vessel - I hover over and click, and the attachment node disappears, but the part is not attached. Sometimes in flight with a vessel with a Kethane part, I will be unable to end that flight and must close KSP. Sometmes, when exiting a flight with a vessel with a Kethane part and returning to the VAB, the parts menu on the left side of the screen will be missing. I don't know if I installed something wrong, or if it's an odd interaction between mods, or just something wonked with Kethane. Any help would be appreciated.
