A script called 'defaultAddBookScript' is used on a number of placed dead NPCs to spawn a skill book in their inventory. Instead of the book respawning every 10 days (or 30 days), the script allows it to respawn in their inventory every time you leave and reenter the area. Is there by chance a way to modify the script to have them respawn at the same rate as everything else? The way it works now is an exploit of sorts, but obviously not a huge one given that the books aren't extremely valuable and don't allow you to increase your skill more than once.
Just a few examples of NPC references that use the script: 000C81C6, 000CED35, and 000DB085.
