TBH I don't see why you shouldn't be refunded.
You was in godmode, in an Admin arena, meaning, you are purposely putting precautions in a NON rp area so you don't lose it, however Orange clearly abused his powers by taking godmode from you, to purposely make you lose the weapon.
Also for anyone to comment, Don't use it if you don't want to lose it.
He was in the Admin area, in godmode, a non RP area, both being precautions to use the weapon without losing it, however the video clearly shows, a fellow admin, un godmoding him to purposely make him lose the weapon, which either way is abuse.
