Some issues with the treasure carried by monsters will be addressed
* You will no longer get the item, "a scroll". These items have been removed and you will now get a genuine, usable magic scroll.
And this from Feb 2000

NPC and Monster Changes
* You will no longer get the item “a scroll”.
I started August 1999 and I had 2 of every direction & colour "a scroll" to decorate my library, and up until the removal of bank box weight limits caused me several headaches, so im positive they were still a part of monster loot up until our cut off point. The fact that their removal was "In Testing" as late as October 27th, and are mentioned again in Feb 2000, well after our cut off point makes me think they should be dropping from mobs. It looks like OSI intended to remove them for sometime but either every time they patched something it reverted it into mob loot, or it kept getting put on the back burner as its a minor thing.
PS: I know im bringing up loads of tiny, minor stuff recently, its not intentional, I am not that much of a pedant, im just stumbling across it while looking for something else .
