Sometimes players make mistakes, such as double clicking on villagers/fishing ships to select all and move them, which crashes the economy and requires a lot of work to recover. Even experts sometimes make this mistake, which can be fatal to the game.
So it is suggested to add a “back to work” button for economic units (e.g. villagers, fishing ships, trade carts), after clicking this button, the unit will return to the previous working state, e.g. a lumberjack return to the tree that didn’t chopping down before, a farmer return to its previous farm, and so on.
