DarkRP F4 Menu Weapons Tab not buyable

[Spytroner]

Hey Guys, im working on a Server derived off DarkRP and we want to use the Customizable Weaponry Mods as Weapons the players can buy.

But we have the Problem that no one is able to buy anything, i get this wierd Error

[ERROR] gamemodes/darkrp/gamemode/modules/base/sv_purchasing.lua:69: Tried to use a NULL entity!
1. SetModel - [C]:-1
2. callback - gamemodes/basewars/gamemode/modules/base/sv_purchasing.lua:69
3. callback - gamemodes/basewars/gamemode/modules/chat/sv_chat.lua:17
4. unknown - gamemodes/basewars/gamemode/modules/chat/sv_chat.lua:256
5. unknown - lua/includes/modules/concommand.lua:54

Now the Model is fine, you can spawn any weapon with the spawnmenu.
I always thought it was a problem with Customizable weaponry 2, but now i have a different Addon that has Sweps buyable in the Weapon menu and they throw the exact Same error.

There is nothing wrong with the way its put in the Shipment Table either the createshipment function works perfectly.

We use ErisF4 as F4 Menu, allthough i dont think it is responsible for this error.

Does anyone know the Reason i get this error, or do you have similar problems that you dealt with?

Thank you guys

So i looked into it again, im really not sure whats causing this problem with the Weapons Tab, anyone any Idea? It doesnt occur with any other Tab
