Seen a bug twice. While “cutting out” steps in a slope using the path tool. For some reason my workers make scaffolding for most of the steps. My process is designate an area for a path 9x4 on the edge of the slope, wait for workers to take away the earth, cancel the job before stone gets placed and then assign an 8x4 zone repeating the steps which creates steps.
The bug seems to happen when workers turn up to remove the scaffolding. What happens, I think, is a worker goes to take away a scaffold but another takes it away before he gets there.
This error message has appeared on both occasions, last entry. The highlighted worker is frozen, battle alert button does not unfreeze the worker, not sure about hunger though.
