Simple question, really - is the Stop function exactly the same as a quest's shut down stage in terms of functionality? Should quest.stop() still be called within the shut down stage's script fragment, or is that redundant? The Stop function's wiki page is quite sparse, so I wasn't able to glean much information from there.

A completed quest still shows as Running with SQV, in my testing. So I always tick the Complete/Fail box, as well as call Stop() in the final stage box.
