Mod: Papenburger Map V2 4K
I know Courseplay isn't official yet, but I've got it to somewhat work for fields. But, I can load all maps except this one with Courseplay activated. It always stops loading at 57%. I can load it without the mod, and I'm only posting this to offer a heads up.

Mod: US Flatlands Karte 4x
Without Courseplay and Autodrive, you really need the AI splines to be able to get around.
