Ok, running with arwens,mod with all modules except onelifer active. Anyone else thats experienced with arwens mod know of any bug fix mods that would be compatible with it?
I know jsawyer, fook, and mmue changes perks and items so they would incompatible, I was wondering if theres any bug fix mods that only changes bugs without item, stat, and perk values?

If you use MMUE and simply have Arwen's mod loaded after I think it should work fine, it'll just override the MMUE changes. Mission Mojave is very much focused on bugfixes and not new features, new content or rebalancing the game, so anything that Arwen's mod overwrites shouldn't cause issues with MMUE I think.
