Any chance you could add Triticale, Rye, and Spelt to the swathable crops list? The yield bonus would be nice.
What map are you playing on? I had debated adding those crops as there are very common but the couple maps I checked with those crops already had them set up for swathing on the map side.
Its The Pichonnière Valley but I did test and it worked and got the 20% bonus. Could you still update the mod description to include those 3 crops?
