The NPC “HK-3 Aerial Dissuasion Unit” in Mechagon seems to be improperly scaling to 60 unlike all the other units on the island who stop scaling between 50-52. I believe that this is in error and that this slippery piece of Gnomish machinery somehow avoided the hotfix.
This was pointed out on the GD forums over here…

And after flying there to check the unit is indeed scaling to 60 for some reason.
