There's pretty clearly a systemic problem right now since the drop of .557 with a lot of quests, many quests that interact with objects and certain NPCs simply aren't doing so, and they were just fine prior to the .557 drop.
If you have an 85, try starting the MoP questline, a few quests in, "Priorities" fails. The bot will run to the Applebloom cider, stands there, and nothing happens. This is all that's in the logs for every interaction:

I've been botting a character from level 1 for the last week and to be honest, I've lost count of the number of quests that are failing with this same behavior.
Just a few quests later, same behavior, on quest: SI:7 Report: Hostile Natives, bot runs up to the very first sign its supposed to right click, and just stands there.
See attached log.
