Ok, so whenever i open ksp and go to the vab. i build a rocket, then i go to modify the staging but the engine icon for the staging is not there so i say oh well then launch it and only decouplers work and i cant right click on any of the engines this is for all engines and the mods i am using are RSS, Realism Overhaul, FASA, Joint Re enforcement, and Hanger Extender
