Update: Solved. I needed to add the UEG source to the character from the Character Portfolio menu.
I recently added the Ultimate Equipment Guide (UEG) to my license package.
Any new character has access to the UEG. For example, I can now add the Glamered item ability to weapons.
However, my old characters cannot access UEG. The Glamered ability does not appear on the weapon ability list.
I hope this doesn't mean I have to rebuild all my characters from scratch.
Help?
