In many cases these XML files are essentially the same and compatible with other mods. Some mods perform "edits in place" to existing files, but if the current file is not what they expect, the edit may fail or produce unexpected results. THERE IS NO WAY TO WORK AROUND THIS FILE CONFLICT, unless you are willing and able to merge the desired elements of the conflicting XML files. The last mod installed "wins" file conflicts by overwriting files previously installed by other mods. The basic problem is one of "install order", which arises from multiple mods which have to use the same XML files to change the appearance of the Menus and Heads Up Display (HUD) in the game. Often times people find their UI is "messed up" after adding one of these and have no idea as to the cause or solution. This is an "umbrella term" that includes everything from the game launcher options and hardware configuration Menus, through the loading screens and "Main" & "Pause" Menus, and into the information you see on the screen when the game is loaded (referred to as the " Heads Up Display" (HUD)), and the Menus provided in the Pipboy, when trading, etc. The way the player interacts with the game is through something collectively called the " User Interface" (UI).
