1. Am I right in thinking that I would need to create a .esp file in which I copy the area where the tree is and then I remove the tree from the area and save the .esp file?
2. Am I right in thinking that the game loads the FalloutNV.esm file first and then loads any extra data files you have chosen afterwards?
3. If I am right in question two then does anything in the plugin file automatically take precedence over the FalloutNV.esm file. For instance, the FalloutNV.esm file has a trailer next to a house behind the shop in Goodsprings. If a plugin file contains the Goodsprings area of the wasteland with the trailer removed and both files were loaded then would it be gone in the game or not?
