Nilbog: You may no longer bind in the plane in hate.
This was the patch where it was changed. I don't see anything on our sacred patch history Bible (
http://www.tski.co.jp/baldio/patch/) that indicates a change to it, and I don't see a bug report related to it here on our forums. Guess that requires some insight from the people that changed it. If this is the same instance then there would be an issue of consistency.
