So I have a monolithic rule that I thought I'd split for ease on maintenance and possibly speed. It's in two halves already so a perfect candidate I'd have thought.
So I back it up and then clone it. I chopped out the bottom half of the rule, no dramas, all good:
However, when I tried the same thing in reverse, it breaks the rule every time. It doesn't matter if I Import or restore the rule, as soon as I chop out the top half of the rule it kills it.
Am I missing something obvious here, or is this a bug? I thought maybe it was deleting some conditions, but it isn't they don't change before and after the rule prune.
