We had the exact same threads about Fulings after Yagluth was killed. I'm sure there will be threads about this when the Ashlands boss is killed. The cycle shall continue.

There's some differences with that though. Killing Bonemass or Moder doesn't enable any additional nightly spawns except skeletons, so it was bit of a surprise to have fulings spread out after taking down Yagluth.

But yeah, once you actually know what's going on, they are just free resources delivered to your door.
