Retaining walls are best built before mining/dumping. They also cannot be built on top of any previously designated mining/dumping areas. Use {0} and {1} keys to raise or lower the wall.
Tugiseinu on parem ehitada enne kaevandamist/maha ladustamist. Samuti ei saa neid ehitada varem määratud kaevandus-/ladustusalade peale. Kasutage seina tõstmiseks või langetamiseks nuppe {0} ja {1}.
