Hi, I found a bug when I used B9 Aerospace and ModuleManager. The bug is with ExsurgentEngineering.dll and ModuleManager.dll plugin. After some research, it is with "primaryEngine", which is used in Engine_Sabre_M and Engine_Sabre_S in B9. When ModuleManager found "primaryEngine" it does not load any more .cfg and sent an error in DebugMode. Sorry for my bad English.
