Auto quest turn accept and turn in, auto flight path and some other tasks are not working when the player has a localized version of WoW.
I know it is "not so easy" to get the proper Quest ID from a gossip text, but I like the way the Classic AddOn "Guidelime" chose to solve that problem. It has a localized database of quest titles, and npc and item names in its backpack (I think that comes from the library "HereBeDragons", I don't know exactly. Some localizations of zone names and flight masters could help also.

Guidelime is trash compared to your addon, but this is one thing that addon makes better and I would highly appreciate that Wow-Pro Guide could recognize localized quests and NPCs, too.

Thank you!
