I wonder if this is just actually not true, but was a hamfisted way of explaining what was happening.

In the low-density mesh which the fox uses, there are more nodes around treasure, and because edges connect nodes, more of the edges in uninteresting space lead towards treasure. So just by picking random edges, or edges away from the player, you are likely to end up near treasure. It's a bit like the is fox moving through a non-Euclidean space which has more volume near treasure.

Because measuring distance by hops would be absolutely daft.
