We heard that players are getting 'Whoa Farmer!' error message when trying to plow, plant, and harvest on Turtle Rock region (Legend of Tengguan farm). We found that it happens when the regular vehicle (Tractor, Seeder, Harvester) is being used instead of the farm-specific one. As a workaround, go to Market and look for the Turtle Rock Coin vehicles and use these instead. Please see screenshot below:
