There are numerous conditions under which Ardour will modify the session
file without confirmation. It would be extremely annoying to continually be
asked if the session should be saved after (e.g.) recording.

However, the specific issue that you ran into is not supposed to happen -
we try to retain references to missing plugins precisely to deal with the
kind of situation you ran into. What version of Ardour are you using?
