V.0.8.3p5 - Hunters stockpiling meat

After one of my hunters picked the carcass from the mountaintop, it appears they grew tired of taking it to their own cabin, a mere few squares away, and proceeded to haul it clear across the map to a different hunter’s cabin wasting months of production time.
This is complete madness.
The hunter’s cabin is atop a mountain and is within the hunting range even. There is a root cellar right next to it. I verified and re-verified that indeed, this was the hunter assigned to this cabin.
The travel time for this walk from the hunting grounds, again just a few squares from their cabin, to the other hunter’s cabin and back was nearly 6 months.
Something seems very very wrong with the math on this one.
