About this mod

LOST, the Load Order Sorting Tool, is a simple and straightforward, lightweight load order manager program for Fallout New Vegas, TES IV and Fallout 3 (you do not need all, though), written in the Python programming language.

Permissions and credits
Now that the Nexus Mod Manager has been rolled out to the public, I see no reason to continue supporting this software. The latest revision should still work just fine standalone, but there may be incompatibilities with newer BOSS versions.

I will not be updating LOST to support Skyrim. There is however an expiremental and entirely untested branch with Skyrim support on the GitHub repository. The tech savvy may attempt to use that, but no promises that it will work - after all I wrote that code months before Skyrim was even released.

Thanks to everyone who endorsed or commented. Argo out.



If you are getting errors when starting LOST stating it cannot load the settings, make sure you run the program as an administrator or install the application somewhere outside of your Program Files folder. Otherwise, UAC will prevent LOST from accessing the required files.

Thanks to Seleuces for the heads up.



LOST, the Load Order Sorting Tool, is a simple and straightforward, leightweight load order manager program for TES IV: Oblivion, Fallout 3 and Fallout New Vegas (you do not need all for it to work), written in the Python programming language. It allows you to change the order in which the game engine loads plugins and masters to prevent conflicts between mods that may cause glitches or crashes. It emphasizes usability and a clean GUI, it's got integrated BOSS support with a GUI for those of you who use BOSS, and, it supports all three games in a single program!

Here's a more complete list of features:

  • Clean and clear interface; mods are divided into two lists: active and inactive so you don't have to sift through all the mods you're not using at the moment
  • Tabs for each game: smooth transition between managing your different load orders
  • Greatly improved mod sorting over the 0.9.x releases: move multiple mods up and down your load order at once, move to top/bottom with a single click et cetera
  • Speed up your sorting by using hotkeys to move mods in your load order (it's really neat in my opinion!)
  • Better Oblivion Sorting Software integration with a graphical user interface for all you BOSS users
  • Comes in both raw Python and EXE format, so you don't have to install any external packages if you don't want to - all you need is an OS and a game
  • Also comes packaged in a neat installer
  • ... and some more stuff I forgot
