I'm definitely noticing a massive increase in greydwarf mobs, especially at night.

I've noticed this too, doubly so when trying to mine out a copper vein. I had to dig out a massve trench around it, and drop 3 campfires at the entrance to keep the horde out. And when i say horde, there were enough that the game started to "forget" that greydwarves are scared of fire and they start hitting them, or ignore em completely.
