I had the same problem. Large group of raiders in my base. dozens of rounds shot, I deal no damage. But they don't do any damage to me either. I can knock them over with my shotgun, but they won't die... unless... I walk behind them, point my gun at them until they put their hands up and surrender... Then they will take damage. Not proud of it, but that's how it worked.

If I had to hazard a guess, do you have Godmode on? It applies to everybody including NPCs when you turn it on.

Is there a way that doesn't affect them?

i dont do any damage to npcs with melee or guns but they can kill me? how do i solve this

turn off pvp

hey man if u have the mod advanced trajectory that is the issue

if you have advanced trajectory make sure the can damage players/pvp is enabled otherwise guns will not damage the player or npcs

Turn off any other "survivor" related mod none of them are updated to work with this version.

If you are using brita's weapons, try different guns. I put 2 mags in a raider from 2 squares away(green outline) and they were unfazed. no animations, no indication they had even been shot. I switched to an smg and put them down in 3 shots. First shot they leaned back, second shot they fell on their butt, third shot they fell down all the way and stopped being highlighted. I also got killed this way once before. Brita's firearms also tanks your fps, so I started using VANILLA FIREARMS EXPANSION (B41)

This fixed it for me.

i have a similar problem but only when i play split screen with my friend . only player one can kill raiders and innocent survivors but play two cant kill raiders at all but he can be killed by them. the best thing my friend can do is just stunt them or know them down long enough for me to hit and kill or shot them. is there a way to solve this? i forgot to add i dont use the mod advance trajectory

how do you turn on can damage players/pvp I cant find the sandbox option

"if you have advanced trajectory"
Do you have this mod installed? If so, you should have the option.

I had this issue with Brita's mod pack. No issues killing hostile NPCs after switching to Vanilla Firearms Expanded
