Does anyone know how many extra spaces a bridge needs in order to be accepted by Isabelle?
The bridge itself is 2x4 squares (vertical) but I already experienced that it needs additional space on land, free from houses, buildings and other projects, in order to be accepted. But how much extra space is required and does it only involve the space within the length of the bridge or also surrounding squares?
I don't want to be surprised again when I suddenly can't place the new bridge, after demolishing one that can't be put back.
