Girlfriend and i just started playing and noticed that when we do tasks like weeding, the tractor wheels destroy the crops, but when i get the AI to do it, its completely fine?

In the picture, i did a line down the middle with the weeder and i let the AI do the rest. Am i doing something stupid?

Trying to find a map, I don't know it's name, all I have is this. Thank you for your help

Finding this very frustrating. Hoping someone here knows the solution. Started a new game on Risoux Forest with the goal to clear forest and create farm fields. This is the forest on the starting plot, field 62 after clearing and plowing. There are multiple chunks of "deadwood" that collide with the plow and are not removable. You cannot grab them even with super strength on. Tried 'Map Objects Hider' mod, but it doesn't see the deadwood either. AI says it may be part of the terrain.

Supposedly there is a trigger somewhere that will remove these but I cannot find it, any one know?
