That sounds like a great modification you've made to the combines and headers in the game! Increasing the capacity and working speed can definitely improve efficiency during harvesting. Players will likely appreciate the enhanced gameplay experience with these changes.
Having a range of capacities to choose from, such as 15K, 30K, 40K, and 50K, gives players more flexibility depending on their preferences and the scale of their farming operations. The higher working speed of 20 for the headers can make harvesting faster and smoother, which can be beneficial when dealing with larger fields or time constraints in the game.
Overall, your edited combines and headers pack seems like it will bring a fresh and exciting dynamic to the game for players who enjoy the harvesting aspect. Thank you for sharing your work with the community, and I'm sure many players will enjoy trying it out!
