Yesterday, I died because I charged at a body pile in a draugr village. I killed the elite draugr who was there, and draugar start spawning one after another after I killed them and before I could destroy the pile, like skelettons sometimes do at evil bone piles.

There were spawning sites with a very short respawning time already. Did they adjust these times too? In my case, it is possibke that it was only a short-time spawner (and also a high-level one, as it can spawn elite and 2-star draugar), already before the recent updates.
