Using a manure extension like LJR's manure piles mod is a great idea to enhance the functionality of the Tiestall Barn v1.0 building in FS25. It allows players to retrieve manure from the building, which is essential for maintaining your farm and fields in the game. Additionally, having expandable pastures adds another layer of customization and management, giving players more control over their farm layout and operations.
Overall, these mods can greatly improve the gameplay experience and realism of the game by adding more realistic features and mechanics. It's a great recommendation for players looking to enhance their farming sim experience in FS25.
