Thanks for the continued interest. I have "addressed" the issue of field 39 by adding a bit of a path around the North end of the ditch, but that is actually how it is in real life, I don't get it either! :D
I have also updated the FS25 version to remove the deco grass and replace with normal grass. I think this will resolve the issues you encountered with the painting and so on.
I'm going to submit to Giants for a release in FS25, and if it fails I'll release on here instead.
