Yesterday evening suddenly my tractor started to float and turn around in the air. He collapsed and returned to the map half in the ground in front of the barn. I also had the time suddenly consisting of 6 digits, for example 03: 114. I also got 1% at the top of each game menu "liquid fertilizer". A restart has corrected this. The Montana map is also very unstable. Even the hired workers sometimes do not want to do their job. Perhaps you can also ensure that you can use several workers per field.
I hope that there will be an update for the consloe very soon. I play the game on a PS4 PRO.
