Quest Issue: The Gnome Take quest seems broken.

[Uradamus]

This is a low level Dwarf Rogue quest given by Jeet in North Kaladim after completing the Rat Patrol quest. You have to head to Ak'anon and find a special scrubber robot, say "628" near him, get a response and then give the scrubber the key Jeet gave you in order to get the package you are supposed to bring back.

The scrubber in question is Scrubber IV who is one of several scrubbers that can spawn in the same rotation as Duster V. Scrubber IV does spawn, but he doesn't respond to 628 and when given the key he just eats it, causing the unfortunate rogue to have to head back home empty handed to restart the quest and get a new key.

I notice that some changes have been made in the past in order to make sure Scrubber IV properly despawns like the others npcs that spawn from the same location so Duster V can eventually show up for the Gnome Wizards who need him for one of their quests. I am wondering if something was broken in regards to Scrubber IV while that was being fixed.
