I'm having trouble with a specific part, the Merlin rocket engines. I can't seem to pinpoint the config file. I think it's "RO_StarShine_MerlinPack", but I'm not sure. If this is the correct file, then I am really confused, because the variants that I want to work with (Merlin1D-FullThrust and Merlin1DVac-FullThrust) are in the config file, but aren't in game. Could someone help me out, or at least point me to the correct forum thread, if this is the wrong place to ask this?
