As one of the original (the original?) arguer against allowing a save in this situation that led to this thread being created I have to agree: The opinion that no save is allowed here is completely wrong.
The why of it still makes no sense to me. I've re-read the decision several times and the summary seems to be to be:
"You still get the save....because".
And then random reasons thrown out as to accidental/magical things that could randomly happen.
I don't understand why magical/random happenstance would fall under a "reflex save", but apparently it does.
As someone said earlier, this just has to be sucked up with a wave of the hand and a DM saying something like "magical fairies appear and move you 10 feet saving your life for no reason at all! Yaaaaay!".
That, or look for a game where the rules are more clear/make more sense.
