And here's another interesting point. If the road runs strictly horizontally or vertically, there are no problems with determining its boundaries. However, when it runs diagonally, you can move along the road itself or one cell above its line without leaving the road. That is, it expands by a factor of 2, and this is not noted anywhere. Moreover, I recently watched a video in which an experienced player rather riskily attacked a group of demons with a scout to avoid leaving the diagonal road – it turns out that not everyone knows or pays attention to this.
