Hello, your welcome.
I just loaded into a new save with easy dev, and store deliveries. I mowed a big chunk of that field, then tedded most of what I mowed. Then windrowed and baled it. I had some FPS drops but nothing crazy. Loaded it in GE and looked around and didnt see anything stuck under the map.
Did you plow that field up and plant a different crop or something that I could try testing? Have you noticed this anywhere else on the map?
