So I see alot of players having issues with ll injected weapons but I don't have that much issue with them.

Maybe because I use a mod called DDLL

Distributed Dlc Leveled Lists by otellino.

Introduction

Distributed DLC Leveled Lists, or DDLL, is a script-based mod for Fallout 4 that dynamically distributes all the weapons from official DLC that the player currently has installed throughout the base game. Being script-based, DDLL has the benefit of not requiring the player to create or use merged patches, rather it injects items into appropriate forms and at appropriate levels at runtime. DDLL also has the benefit of not requiring specific DLCs or Creations - it works dynamically in the background, adapting to the player’s currently loaded content.

It has 3 modes standard, wacky, unhinged.

You can read about it here:

https://otellinomods.com/wiki/distributed-dlc-leveled-lists/

it's a tiny master file and it makes the game so much more unpredictable. You never know what the next mob of enemies are going to wear or equip.

I just wish otellino updates this fabulous mod to anniversary edition but strangely I see vendors sell 12.7 weapons which are from Sea Scavengers cc that are not supported by this mod.

Recommended mods:

Tumbajamba's armor collection; mm, gunners, synths etc..

Weapons of the wasteland series; I use all of them except revolvers.

Combined arms and expansion: I don't use this mod but its a very cool weapons mod, adds 17 high quality weapons to LL but I read it has some texture issues.

Eli's armor compendium

Second solution: stay out of the leveled list injection range

Crashes only happen when the enemy npcs spawn with LL weapons with different customisations. Armors don't have that much impact. The range is between level 5 to level 30.

You can test it at beginning of the New Game. After existing the vault using Cheat Terminal put your level to 75, teleport to boston library move to boston commons. ( I cleared the whole boston from enemies in 2 hours without saving and without Crashing, entered and exited combat zone, goodneighbor, DC etc.. I didn't even use fps plus, smooth as butter 🧈 )

Use Enemy Scaling Revamped mod if necessary. It might help but makes enemies so much stronger.

Hope this helps 🙏
