When items on your to-do list aren't completed as scheduled you'll see other kinds of objects on your land:

1. Incomplete tasks (delayed): fractured land, damage, and unfinished projects such as cable cars, roads, bridges, tunnels, etc.
2. Late tasks: continuations of previously completed landscapes, for example the end of a cable car, end of a bridge, end of a road, etc.
3. Canceled tasks: cross-marked blocks, for example ditches, fractured land, etc.
