In Pandaria during the quest “Scouting Report: Hostile Natives”, there are interactable objects called “Lifelike Jade Statue” that are meant to be “Inspected”. With the new INTERACT button, it would be expected that it would work for the inspection, but it does not.
Additionally, immediately after the statues, you need to interact to talk with “Widow Greenpaw”. She can’t be interacted with using the INTERACT as well.
