Today farangkao gave me an idea how to deal with missing account name in saved variables or maybe I should say how to deal with broken GetDisplayName() function.

Just put this code to the main chunk any of your .lua files:

local displayName = GetDisplayName()
if displayName == nil or displayName == "" then
   if GetNumGuilds() > 0 then
      displayName = GetGuildMemberInfo(GetGuildId(1), GetPlayerGuildMemberIndex(GetGuildId(1)))
   else
      displayName = "@" .. GetCVar("AccountName")
   end
end
 
function GetDisplayName()
   return displayName
end

And voilà, your saved variables with @AccountName works again.
