If the character has a saved "Vault of Archavon", the addon's table suddenly stop working.

The error message generated is the following:
Message: Interface/AddOns/SavedClassic/SavedClassic.lua:935: attempt to index field '?' (a nil value) Time: Mon Feb 19 10:07:11 2024 Count: 3 Stack: Interface/AddOns/SavedClassic/SavedClassic.lua:935: attempt to index field '?' (a nil value) [string "@Interface/AddOns/SavedClassic/SavedClassic.lua"]:935: in function <Interface/AddOns/SavedClassic/SavedClassic.lua:934> [string "=[C]"]: in function 'sort' [string "@Interface/AddOns/SavedClassic/SavedClassic.lua"]:934: in function 'ToggleRaidTable' [string "@Interface/AddOns/SavedClassic/SavedClassic.lua"]:822: in function <Interface/AddOns/SavedClassic/SavedClassic.lua:819>

This bug is found with the spanish language. Anonther extra info that should be useful is the next error trace:
Locals: a = "Cámara de Archavon" b = "Naxxramas" (*temporary) = nil (*temporary) = nil (*temporary) = "attempt to index field '?' (a nil value)"

The real name in spanish is "Cámara de Archavon", so this is probably related to the bug reason.

It seems that Blizzard changed zone name or instance name of 'Vault of Archavon'.
Stealth patch, as always.
Thank you.

Cured. 2e4c002(3.4.3)
But abbreviation break may occur.
Needs further investigation.
