Stolen Shipments is a new quest that can be picked up from [npc=187758] in central Orgrimmar (to the left of Grommash Hold, if you're looking at the Hero's Call Board out in front of it). Next to/behind him is a bunch of random stuff like watermelons and a drink, and a cart with some boxes in it. [npc=188655] is another new NPC related to this quest, seen standing in the corner fiddling with something in her hands endlessly.
[npc=187775] is the target of Stolen Shipments's objecctive. You'll find [npc=187775] at the base of the Zeppelin Tower for Boren Tundra / Thunder Bluff, on the Borean Tundra side. (The Zeppelin Tower is almost directly behind Grommash Hold, but up on the higher-level ("altitude"?) section of Orgrimmar, near the Flight Master [npc=3310] and Riding Trainer [npc=44919].) As you approach him, you'll see he's holding a highlighted box, [npc=187987], and he will say:
Don't mind me, I just wanted a peek!
Use [item=191408] (in your bag or on the quest list) on him, and he will say:
Not another pie!
Though I'm highly disappointed it didn't really explode... Like, I wanted it to be a maaassive affair, lol.
Pick up the [npc=187987], return to [npc=187758], and turn in the quest!
The follow-up quest he gives you is called Idling Pie.
Stolen Shipments/Idling Pie and all these accompanying NPCs seem to be new additions, implemented with the 5/31/2022 9.2.5 patch.
