The entry on the vault has it listed under Final Destination, as I'm sure that was the original base stage judging by the .rel. I have it over 75m though, so it's renamed STGDONKEY.

If you wanted to replace P:M's saffron, just copy and rename it "STGTENGAN_1" "STGTENGAN_2" and "STGTENGAN_3" and replace the files inside "melee."

Just clearing any confusion.
