Cannot spawn any NPCs?

[THROBBING]

When I spawn any NPC that isn't from VJ Base, the model appears for a second then disappears. The NPC is still there, its shadow is visible and it still acts like an NPC but it's model is gone. In the console it gives this error :

[ERROR] gamemodes/sandbox/entities/effects/propspawn.lua:105: attempt to index field 'SpawnEffect' (a nil value)
1. unknown - gamemodes/sandbox/entities/effects/propspawn.lua:105

It gives this error like 150 times a second and keeps going unless the NPC is deleted. It only does this for NPCs, not props or entities or anything.

It shows no errors in the problems list, and in the Lua Errors screen it shows the same error from console, but it says it can't find where the problem is coming from; meaning it can't figure out if it's coming from an addon or not.

I have reinstalled the game and verified integrity of the game files, has anyone encountered this issue and how can I fix it?

I have the exact same problem, can anyone help?

This has happened to me as well. idk why? Have you guys found any solution?

[THROBBING]

no

ATTENTION: The mod that is causing the error is the ADMIN LONG REVOLVER
Idk why tf that mod is ♥♥♥♥♥♥♥ everything up but it is

I found a fix :)
The long admin revolver is likely the problem for you, but it might be something else - no worries!
The reason this happens is because a script in one of the addons you have installed breaks the SpawnEffect, all you have to do is hold C -> Drawing -> Uncheck the box "Draw Spawn Effect" Or you can fix the addon's script by fixing SpawnEffect :) Hope this helped!

EDIT: If you get any other errors, go to C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\gamemodes\sandbox\entities\effects then open "propspawn.lua" with notepad, in notepad, press ctrl+a, then paste this code instead, then close notepad and it will ask if you want to save, press yes and MAKE SURE TO REJOIN THE GAME IF YOU ARE ALREADY IN A SERVER!

I know I'm not the best problem solver, there should definitely be a better way to do this!
