I'm not so sure about that. In both games I have played, I get an occasional bark scorpion up there. I suspect that the Giants in town followed the courier from over near the Yangtze Monument/Abandoned Hut. I had to abandon that hut myself when two of the things showed up there!
I have seen these Bark Scorpions each time I have done the Tutorial. There are usually two near the graveyard path. They don't show up until the you get the quest to fetch the ingredients.
Seriously? That's weird for me, then again I tend to play the hell out of each character I start before making a new one, so I don't restart very often, if much at all. First time out, I never had any bark scorpions, but that might've been because I skipped the tutorial quest for ingredients fetching on that one. I just wanted to get to shooting things in a hurry. On my current, there is one and has only been one. There's supposed to be more than one on that path?
The first on i saw chased me for a while up to the graveyard i left him there hoping he wouldnt be to much of a problem but later i found in good springs the one i killed with the fence. since then every so often a new one shows up. i have noticed that the body of the old on is always gone.(i was thinking about piling up the bodys and taking a pic.)
Every 72-74 in-game hours, a given area (called "cell," basically either an indoors area or a single section of the overworld map) will reset, meaning items are restored to original positions and any and all killable creatures that aren't unique will "respawn," typically in the spot where the body last lay when killed. That new one that shows up is actually the same one that followed you, only just respawned back into the game since you were away from the area for long enough.
