Western Plaguelands 90% bugged

[zawa]

Playing Classic, Zygor Guides has been extremely buggy past 40. Especially past 50. But Western Plaguelands is almost 100% bugged. I'd say 90% of waypoints are off — sometimes entire zones off.

What's the time frame on fixing some of these high level zones?

EDIT:

Fairly certain at this point that Western Plaguelands is completely bugged. All the waypoints are in Tirisfal Glades
