Well, this is a new one. The recently added 
Grizzly Hills Packmaster mount is a nice alternative for the old yak, with its repair and transmog vendors. Now, while players were mildly annoyed that the vendor locations were swapped from the yak, there might be a much bigger issue with it, and it’s much more hilarious too!
Big Bear, Tiny Vendors
So, it’s possible that the Packmaster isn’t really packing its vendors away properly when it leaves. The mount seems to be leaving behind tiny versions of its vendors, as spotted by notaburneraccountk.
Is It Real?
Now, we’re not sure these are actual tiny vendors, as the post is labeled as humor/meme, and you can’t really see what the spots are, but the bear is leaving something behind! It may just be bear poop, but it could also be actual miniaturized vendors! A few players actually commented seeing many transmog icons on their map but no actual vendors around, which could be these tiny spots.
It’s difficult to actually see the vendors themselves, and perhaps it’s just their IDs or icons that are being logged. But, there’s definitely something of them being left behind, and the game may be processing that as the full NPC! Or it’s just a joke and the bear is leaving… something else everywhere it goes!
So, if you have the bear, take care not to litter too much, whether it’s tiny vendors or not!
