A recommended best practice for resolving mod conflicts in Bethesda RPG games (Skyrim, Skyrim Special Edition, Fallout 3, Fallout New Vegas and Fallout 4) is to use the xEdit modding utility to check for conflicts between mods that alter similar or related parts of your game, this enables adjusting your mod load order to resolve small conflicts, or deciding if it’s best to disable a conflicting mod and start a new game to prevent issues with game stability.
