Rack-9 Firebug Issue

[NolanHewitt]

The firebug variant of the Rack9 shotgun doesn't work in zombies, attempting to buy it will give you nothing, and the model doesn't appear in its purchase spots. This was an issue in a previous version of regular IW but was fixed with either a patch or hotfix. I'm not sure if its just that PC never got these fixes or if something about this mod disables online-only hotfixes that were never made into patches.
