So i just modified a texture included with the Metropolitan Police Station pack, namely the wanted poster with Fozzy's face on it (I put the face of some i dislike on it, because that's how petty i am)
The problem is, the modified poster isn't showing up in game, it still has the original face and text on it, even though no trace of this can be found in the game files.
 Help?

I'm using a mods folder by the way
