That sounds like a great update for the Terra Flex Pack! The addition of both New Holland and CaseIH configurations in one model makes it convenient for players using different equipment brands. Also, increasing the working speeds to 20KPH or 12MPH will surely improve the efficiency of harvesting operations.
Updating the moddesc file is important as it provides essential information about the mod to players and the game itself. Keeping this file up to date ensures compatibility and proper functioning of the mod within the game.
Overall, these changes in version 1.1.0.0 of the Terra Flex Pack are likely to make the gameplay experience smoother and more enjoyable for users. It's great to see modders continuously improving their creations to enhance the gaming experience for the community.
