When a resource is created, its GUID is not generated randomly, but based on file path and file name.
**Two examples:**
- When you create a config file named "test.conf" in a project root folder, the GUID will always be 86C36D99914265F8.
- When you duplicate 21_GM_Eden.conf as a basis for your own scenario header (without initially changing its name), the new GUID will always be 59AD59368755F41B, incremented by 1 from F41A.
**Whenever** modders happen create a resource with the same name in the same place, it causes a GUID collision and silently makes the mods incompatible.
There is no reason for this behavior: The purpose of GUIDs is not to serve as a hash of the file name, it is to uniquely indentify a file completely regardless of its content (or worse, name/path).
Instead, GUIDs should be generated randomly - this does not conflict with their purpose and avoids GUID collisions. Random collisions are not a problem as there are 16^36 valid GUIDs.
