Hi all,
I've spent an evening trying to bring some very, very old vehicles from 0.21 or so into the latest KSP, and so far I've managed to work out how to remove older parts from vessels by manually editing the files in notepad, and can now reload them in the VAB. However the next step has proven trickier; I want to return some old completed vessels around the Mun etc, but copying and pasting these (also edited) into the "persistent" file leads to issues where the vehicle appears correctly on the map, but I can't Fly them, and the game seems broken because I can't launch or load anything from the VAB etc. I tried doing it manually, as well as using the Kerbal Savefile Editor to try and automate it, but neither makes any difference. It's not individual parts blocking it, does any one know if there's a more up to date vehicle-importer, or what the issue might be which is blocking me? Thanks!
