Randomly building stops while building rabbit’s ear part. Hearthlings eventually don’t go to build scaffolding or ladders to build ear part. I found this situation is frequently occurred under following conditions.

  1. Save/reload while building is incomplete
  2. Due to speed of placing slabs much more faster than placing scaffolding and ladders, workers stuck at the top of monument. After rescuing workers by building manual ladders, building does not continue.
