writing scrolls of chaos resistance is misinterpreted
If you attempt to write a scroll of chaos resistance with a magical writing set, the game misinterprets this and thinks you want to write a scroll of balance instead.
edit: doh.. the reason is of course that the name has been changed to corruption removal! Still, it would be nice if asking to write a scroll of "chaos resistance" would result in an attempt to write a scroll of corruption removal, not balance. The same goes for wishes.
