How to reset the economy.   You need to go to the settings (in the upper right-hand corner of the VTC.World client or on the VTCW website)  and on the tab "VTC.World Gaming Profile" toggle the slider (separately for ETS2 and ATS)  
After restarting the client, you need to start the multiplayer and go to the game world.   Note: Resetting the economy does not reset your stats and balance. Update your current economy to match your new level and acquired skills in the game. Active delivery will be dropped into history with the status "No Data" (this does not apply to deliveries of World of Trucks). The goods will return to the delivery menu if it’s gone.   To see the results, you have to enter the game world online.
