Damn invisible walls!

[MrWolf]

I ventured into Bleak Inlet and shot up some Timberwolves.  Two of them ran off with an arrow in each.  Found one, no arrow, so it must be around somewhere.  Finally found the other one when the weather cleared enough for the crows to come out.  It's in the yellow circle below and I can't get to it because there is an invisible wall just below it.  Too bad the invisible walls don't stop the wolves!  I expect my arrow will be sitting there forever once the timberwolf despawns.  Or maybe I'll get lucky and it will magically pop into an accessible location.
