Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi I'm trying to make an item switch event for itemrack that switches my offhand(spell stone) to another offhand (tome of shadow force) when used and I can't seem to get the events working correctly, I can't even get the built in insignia event to work so any help would be appreciated, thanks

assuming it should look something like this based off of the insignia switch event?

if arg1=="Major Spellstone"
then
EquipSet("tome") end

ItemRack Events are no longer working on this server (since sometime in Oct/Nov), my guess is they locked something on server side.
It works fine on other popular server(s).
I have tested it on Mac and PC, no other addons, clean WTF, WDB, different characters, wont work on Nost.

I've had no issues getting ItemRack events working (that would be surprising as it doesn't do anything special and there would be scores of addons not working if events weren't firing for the client).

Are you sure you both ticked the "enable" checkbox and clicked the question-mark icon for the event in question to assign it a set?
