Weapons Not working after changing game to a classic Template

So first off, I apparently reskinned some gun free models.
Yeah, I know it sounds odd, but yeah. I used the tommygun model as a reference for my guns.

And they worked fine in a different game, well seemingly on NPCs.
But As I tried the same models in a different template (The Classic Baseplate), the guns just didn’t work.

Basically when I tried to kill NPCs, the npcs wouldn’t die. They wouldn’t even react to the damage if they were coded to react.

Thats Pretty much the issue it seems. Other tools seem to work fine though, like some other weapons like the classic sword.

I don’t really know what I did wrong, Maybe There’s something different about the classic baseplate? because I’m pretty sure I used the guns on the morden baseplate, But I cant be 100% certain. But I swear something is up with the (Classic Baseplate) Template.

If someone can give me suggestions, maybe there is a setting I didn’t change, or something else. The game is set to R6, and I Believe the guns work on R6 Players and NPCS, but I don’t know what to think.

Basically, After switching from the Morden template “I THINK” to the classic template, they just stopped working like that.

I’ve always seemed to have this issue, sometimes weapons stop working after I transfer them to a different place. I just Don’t understand it.

NOTE: I did change the settings of the weapons, but that won’t help much because I have no idea what I am doing wrong here.

I think there may be some sort of settings I need to configure in the classic baseplate. Because I’m pretty sure these weapons seem to work on the new baseplate.

Like the 2021 baseplate.

I don’t understand, maybe the streaming mode is the issue?
