Who cares about the mod, that's not the real answer--just a way to cheat around the vanilla game settings. Irrelevant. As for being hunted--yeah, depends on how fast you kill them. If you get to a spot they can't reach then you won't get many and the hunt will eventually end. If you stand out and fight them the whole time they will keep spawning and you'll get quite a few. It's a fun event, something that can hit anywhere (not just the mountains). Keeps you on your toes. When I first start searching for silver in the mountains I make sure I dig a significant hole when mining, one the wolves can't normally climb down. When the hunt begins it's not uncommon to have a handful pacing around the edge of the pit where I'm mining, with one that occasionally falls in and I have to kill it. All in how you plan, like everything in this game.
