so today while playing KSP i made a little mun base with a docking port on the top as seen here i decided to dock a beacon on top of the base so i made this as u can see theres a docking port on the bottom and RCS to fly on top of the mun base.ive land on the base like five times now but they refuse to dock, ive tried turning off RCS and SAS but that dosnt work. my therory is that the left over decoupler on top of the base is blocking the two from docking. is this true? what can i try to make the 2 dock. also heres a cool pic i took for fun:)
