Crash fixed in 1.11.240.

Version 1.04

The lag issue when completing transactions has been resolved.

If you are a hoarder like me (original author tryname, the same below), carrying about 20,000 items and rarely clearing legendary weapons and equipment, then congratulations, you are lucky. Your barter menu with the merchant will be very stuck. This is because the trade menu will run twice to update the list every time you operate it. This mod solves this problem and allows you to operate smoothly even if you have a large number of item types in your backpack.

My own testing of these is limited. If you encounter any problems using it, please let me know.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
