Need help with deactivating a cheat and deleting items!

[Oszilgath]

Hi,
i hit "Insert" or "Delete" severeal times while trying to figure out how to build at the upper floor. A few moments later I recognized that im overloaded with about 2800kg of weapons and ammo.
I don´t want to use them and I don´t want any other player to use them.
So here are my questions:

1. Is there a way to deactivate this cheat?
2. Is it a "build in" cheat or does it come from a mod?
3 Is there any way to despawn the weapons and the ammo?

Installed mods are Hydrocraft, HuntingMod, Nocturnal Zombies, ORM Real Gun Mod, The Walking Dead Prison 1.3 and Silencer, i think.

At least i know how to build the upper floor meanwhile :D
