So while trying to do the Noah’s Ark quest earlier - I couldn’t find any Stags. I found them the other day, specifically two, which I killed and waited for, and they never respawned. I went back again yesterday and today, hoping to finish the quest - but the Stags still were not there.
I went and checked the rest of the map, and couldn’t find any more.
So either these things have only one spot they spawn in, and their spawn rate is bad, or I just can’t find them. Maybe I’m supposed to hunt them in the Wilds? I don’t know, I checked every entrance to the map and they just weren’t anywhere.
