Oh, pity. Yes that was pretty much what I was thinking; since submitting
the form doesn't go anywhere new I was imagining it would be possible to
just tell it 'nothing changed'. Silly me.

Not keen on them myself. The page is very simple but saving cycles is
good. One day we will be able to cache saved cycles and get them all in
a rush when we really need them for Doom XXIV; return to the son of the

Yeah, there's plenty of ways around it but simply not needing to do it
is always the easy way out :-)
