Hey, maybe this is an older bug but I found it made hunting alot easier.
But it's a bug nonetheless, or atleast I'm assuming so.
I found a boar near the shore, started slinging it, sitting in my boat. After two hits it went into flee, so i started chasing it for a few final punches, it was stupid enough to run into shallows, and after bumping into it then it just stopped fleeing (i'm assuming I was blocking it), so i ran back a few feet so I could punch through it's defense, and to my surprise it started following me, i ran around for several minutes and it didn't stop.
So i loaded up my aim meter, hit it once (dealt damage), and THEN it finally started running again, punched it twice, 7k LP.
