I've noticed something a bit odd, and even though it doesn't cause any problems it caught my attention.
When you're editing a script with the Script Editor open and you do a save, Opus will save a folder inside /temp containing the whole script package you're editing. That's normal so far, since I guess it uses that for the Script Editor and related tasks.
But it also starts saving copies of a bunch of other, unrelated scripts, even some that are disabled. Why is that? I can't find a pattern for what's special about those scripts, but on a quick check they always seem to be the same ones.
