Field 14 can no longer be detected by the ingame ai or GPS and crashes Courseplay
You can fix this by rounding off the upper left (northwest) "corner" of the field.
I'm having the same issue :( works fine until Courseplay throws a tantrum with "Field detection"
Rounding off the Corners works or recording a custom field with courseplay worked for me both.
I had the same problem, I ended up painting in a little more grass along the roadway and it seems to have fixed the problem, never crashed Courseplay for me though, just got stuck in "Field Detection" when starting an existing course.
This worked for me as well.
