* Official protected highways use a marker at each tile corner which will protect all 4 tiles around them. These markers are called [[Catseye|Catseyes]] and [[Waystone|Waystones]]. Official highways are used by wagoners to transport goods as well as for general transportation purposes.
*Repaving a tile is possible without removing the catseye or waystone:
** Activate the material needed for the [[pavement]] type, right-click a paved tile and select ''Re-pave'' > ''Tile'' or ''Nearest corner''
