Hellow there,
Hope you are doing well? An issue was Encountered while looking to complete the pet tamers achievement. None of the NPC’s are offering the quests. Ex. Battle pet tamers: Pandaria, is not available at Sara Finkleswith. The same goes for Pandarian Spirit tamer and so on. NPC Audrey Burnhep in SW is not offering any quests only a stackable orange tabby cat that since yesterday is not stackable anymore 
Could you fix this? Thanks in advance.
Have a great day,
