Hi Diazo, sorry, my work-life had the best of me, yesterday. As promised I will send you the complete log file as a pm in a few secs. I got the following error message 104282 times: [LOG 00:23:39.257] AGX RTQueue Fail 1 System.TypeLoadException: Could not load type 'System.Func`2' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. at MuMechModuleHullCamera.DeactivateCameraAction (.KSPActionParam ap) [0x00000] in <filename unknown>:0 at BaseAction.Invoke (.KSPActionParam param) [0x00000] in <filename unknown>:0 at ActionGroupsExtended.AGXFlight.ActivateActionGroupActivation (Int32 group, Boolean force, Boolean forceDir) [0x00000] in <filename unknown>:0 Busy litte beaver... This is what it looks like in-game: I hope it helps to track down that nasty bug. Good hunting! 0level
