When you say you set it to a "different number" are you referring to the point ratio for the destination?
As for the raid attendance percent bug, I think I have an idea what's causing it. I'll have to look a little further, but I think i know what's causing it.
Yeah when you go into the destination. and you have all your listings.
and lets say i moved Honorary Member above app, and app was set to 1, but Honorary Member was set to 0, it reverses those 2 numbers.
Setting app to 0 and Honorary Member to 1.
Or if i add others ranks as well, what ever the one before it is, the number gets switched between the ranks it moves to. EVEN if i moved it all the way to to top, it would bump the Destination value to 0 or 1.
