Ever since the odd bugs with databases on CD turned into just not bothering, some classes have had rather prominent features broken. The one I know most about is Silverstar's "Moon's Hand"
Now I don't expect an easy return of the whole on-equip script. However I imagine that it wouldn't be impossible to take parts of scripting from Greater Magic Weapon and convert Moon's Hand into an activated, self-targeting feat that could bestow these effects on a 24 hour duration, with an unlimited number of casts.
That will likely be the solution. However, changing the feat to allow you to target/buff your weapon requires a hak change.
I could kludge it with a /command in the interim.
My name is Goat and I approve this message. (As a sexy Silverstar as well)
