Sower is sowing over previous track

[nifty1946]

hI Folks,, something new to think about,, i've been on 17 since about day `1.. Now today when sowing Radish on Lawfolds farm the sower keeps going back over the row that it just finished planting,, I have to wait and watch the damn thing and set it on the correct track,, at the end of the new row it just does the exact same thing again,, resowing over it's previous track,, damn annoying.. Any ideas are appreciated,, Thanks.....I did notice that this only happens if I shut the game down for a while and then go back online to farm again,, the sowers start along the correct path but then turn the wrong way at the end of the row..
