@Snark thanks for you quick reply!
Watch out for the difference between part "name" and "title". From my understanding:
Name: The hidden internal part name
Title: The name displayed to the player in game
From a quick search through the configs, I find the following parts with "Category = none"
Title: Mk1-2 Command Pod Name: Mark1-2Pod
Title: Mk1 Command Pod Name: mk1pod
Title: Probodobodyne HECS Name: probeCoreHex
Title: Probodobodyne OKTO Name: probeCoreOcto
Title: Probodobodyne OKTO2 Name: probeCoreOcto2
Title: Probodobodyne RoveMate Name: roverBody
Title: Probodobodyne Stayputnik Name: probeCoreSphere
Title: RT-10 "Hammer" Solid Fuel Booster Name: solidBooster
Title: RT-5 "Flea" Solid Fuel Booster Name: solidBooster_sm
Title: Rockomax Jumbo-64 Fuel Tank Name: fuelTank3-2
Title: ROUND-8 Toroidal Fuel Tank Name: toroidalFuelTank
Title: Rockomax X200-16 Fuel Tank Name: fuelTank2-2
Title: Rockomax X200-32 Fuel Tank Name: fuelTank1-2
Title: Rockomax X200-8 Fuel Tank Name: fuelTank4-2
Title: A potato like rock Name: PotatoRoid
Title: TR-38-D Name: size3Decoupler
Title: TR-18D Stack Separator Name: stackSeparator
Title: TR-2C Stack Separator Name: stackSeparatorMini
Title: TR-XL Stack Separator Name: stackSeparatorBig
Title: Rockomax Brand Decoupler Name: decoupler1-2
Title: TR-18A Stack Decoupler Name: stackDecoupler
Title: TR-2V Stack Decoupler Name: stackDecouplerMini
I assume all of these would have old configs floating around, expect for PotatoRoid of-course!
