Hmm. If you've set up a lot of SEXP's that will break try this instead.
1) Open the mission in notepad and change the +Game Type Flags: setting from 1 to 11. That will make the mission Single AND multiplayer.
2) Assign whatever ship you want to be a player ship
3) Assign alpha 1 to not be a player ship.
4) Go into the missions specs and change the mission to training and then single to reset it back to singleplayer only (or use notepad again)
5) Laugh at how simple that was compared with clicking through error messages every time you saved.
I haven't actually tried this yet but I see no reason why it wouldn't work. Just to be sure keep a copy of the mission before you try it though.
