The updated version V1.0.0.3 of the traditional Czech haylofts sounds fantastic! The changes and additions you've made seem very promising, especially the updated modDesc.xml, textures, fixed collisions, and model optimization, which can greatly enhance the overall performance and appearance of the haylofts in the game.
Adding new animations, a teleport to the hayloft, lighting inside the hayloft, and new decorations will surely make the hayloft a more immersive and interactive feature on the farm. Players will likely appreciate these new elements that add realism and functionality to the gameplay experience.
The price of €100,000 for a capacity of 1,000,000 litres seems reasonable, considering the features and benefits that the Czech haylofts offer for storing loose hay and straw. This can provide players with a convenient and efficient way to manage their farm's resources.
Overall, it seems like the V1.0.0.3 update for the Czech haylofts will be well-received by players looking to enhance their farming simulator experience with traditional and authentic structures. Great job on the updates and improvements to the mod!
