Very recently, my "hobgoblin doubled its population."
That simply couldn't have happened (as far as I know, and I'm even checking specifically... I'm curious myself), maybe you're confusing it with the month of hobgoblins? Or, at worst (maybe...), that even such a population exists, and it doubled the growth rate of hobgoblins in the castle? Personally, I've never heard of this population at all.
By the way, please explain the nuances of monster weeks and months to me!
I've discovered a terrible gap in my knowledge.
What specifically would you like to know?
