This is getting super intense! So I used an alt to luer the boar away, and started shooting the fox. Suddenly it breaks through the signs, walks right through around the fence and though hole in the fence made by the boar, and knocks me out (I had no idea it could do this). So I just waited until I woke back up and ran as far away as I could.
So why is it that foxes have path-detection AI, but we don't? That's not fair...
