Back in September 2016 there was discussion about problems saving a game because there are additional checks carried out on the validity of the code. I have just been caught out by this issue (undefined function because of misnaming), so perhaps now is the time to discuss fixing it? The Pixie's comment at the time was:

I have a feeling this can happen if you have a script missing a quote or a curly brace or something. If the script runs whilst playing the game, you will get an error, but if it has not run, you will not see the error and not realise there is an issue. Quest seems only to check when saving a game, rather than when saving in the editor, when it would be useful. I could be wrong on that, though.

What are the issues in making the 'editor save' and 'user save' checks identical?
