I have been faffing about trying to sort out why my Mercury mail server thingy what I am playing with has been deleting junk mail instead of simple passing it, annotated, to a dead letter box. Then I accidentally told a rule to move down one. Lo and behold it moved below a rule with no title. It didn't have any tests to do either but it did have an action. 3 fucking days!!!!! A bit naughty that is. I am not sure the rules editor should allow you to save the default offering accidentally like that. It could be naughty.
