Hearthling can get stuck on log pile

When I started my very first game, I found that Hearthlings can get stuck on a log pile on occasion. Like so.

Steps to reproduce:

  1. Start a new game.
  2. Cut down a lot of trees around your camp.
  3. Start cranking out log piles at the carpenter.
  4. Place many log piles in two or three rows.

Expected Results:
Hearthlings move aside/can get down a a log pile by themselves.

Actual Results:
They can’t eat lunch because they’re stuck.

Can be solved by harvesting the log pile.
