Invisible objects in Field No. 26 PeterVill Farm

[Leg_iron]

I am currently trying to harvest field 26 on PeterVill Farm using the in game New Holland CR90. The combine has completed once around the field with no problems. On the 2nd time around the field, the combine hits some invisible objects that are in the field & the front of the combine is lifted off the ground. I can eventually manage to get the combine off the object. But then it encounters more objects further along in the field.

I'm about to harvest that field with a smaller combine, I will see if I encounter the same thing.

I didn't find any hidden objects in the field, however, some of the trees are hanging over into the field a bit and my combine got stuck in those. I will seed a strip of grass on the north and south side of the field and that should take care of that problem.
