The One Season mission, which promises us more than an hour of non-stop play, is unfortunately (too) often prone to AI bugs. Between cars crossing and destroying crops, and workers who run into you in silage, the end of the mission can be particularly complicated. The proof in pictures in this long video of the said mission.
You also have bugs, come and talk about it HERE on the forum.
