* As with [[flattening]], when lowering a tile levelling will stop once rock is found in one corner. Since levelling typically takes or adds two dirts at a time it is possible to repeatedly select level to remove the one dirt from the corner which has not hit rock.
* With at least 70 digging skill you can level resource tiles, such as [[clay]] or [[tar]], as long as no corner needs to be raised. You will get dirt for lowering the corner instead of the resource. If a corner needs to be raised you will receive the message '''Some corners can't be modified''' and the levelling action stops.
