"is dependent on downloadable content" ?

[zombietop 33]

So I have MAS and RHS running, added to vendors and all that good stuff. The items can be purchased, spawned, used, and such. Yet I go look at my log and it is spammed with 

Warning Message: You cannot play/edit this mission; it is dependent on downloadable content that has been deleted.

It obviously isn't stopping me from using the items in game, but there is much spam! Is there a way to fix this, or just ignore it and let my log file go ape shit?

Open your mission.sqm and add each item to addons:

class Mission
{
    addOns[]=
    {
        "exile_client",
        "mas stuff",
        "rhs stuff",
        "more stuff",
        "etc"
    };
};
