GetDisplayName is fixed - However addons will lose their saved variables again.

[Flamage]

The GetDisplayName() bug is fixed and now we can return to a world of normalcy. Rejoice!

The downside is that your addons will have lost all of their SavedVariables again (unless you were storing these manually or your users were using zgrssd's Display Name Fix addon).

Fortunately, the data isn't lost, and I added a routine in Librarian to migrate the data back to its rightful place.

Modify it to work with your addons as you will:

if Librarian_SavedVariables["Default"][""] ~= nil then
	Librarian_SavedVariables["Default"][GetDisplayName()] = Librarian_SavedVariables["Default"][""]
	Librarian_SavedVariables["Default"][""] = nil
	SLASH_COMMANDS["/reloadui"]()
end

Note that Librarian_SavedVariables is the name you gave your saved variable parent, for example:
self.localSavedVars = ZO_SavedVars:New("Librarian_SavedVariables", 1, nil, self.defaults, nil)
