Do monsters around destroyed nests and the nests themselves respawn?
So there are these 3-4 nekker nests not far from each other between Reardon Manor and Benek signposts. I remember killing all the nekkers and destroying all the nests. Yesterday I was travelling through the same area and suddenly saw that there're bunch of nekkers around, dismounted Roach, killed them all and when I approached the nests they had the destroy option. Checked the map and icons for all the nests were grayed out(meaning they're already desstroyed). Do destroyed monster nests respawn?
Yes, destroyed nests and monsters respawn over time.
