Bug Fixes and Minor improvments

I recently learned something intriguing about Unity terrains. Each terrain in Unity has an associated "terrain data" component, which holds all the essential information about the terrain's heightmaps, textures, and other properties. While duplicating entire levels in Unity is generally possible, duplicating terrains is a different story. When you duplicate a terrain, it retains its original terrain data, meaning any modifications made to one instance of the terrain will be reflected in all instances sharing that same terrain data. This led to an unexpected issue in my game where the first and second levels appeared identical. It turned out that I was unknowingly modifying the terrain with the same terrain data for both levels. This experience highlighted the importance of creating unique terrain data for each terrain instance to ensure distinct and diverse levels in the game.
