Fuelweaver does not grant unlock to Wilson

local function AtriumOnKilled(inst,data)
    trackattackers(inst,data)
    for ID, data in ipairs(inst.attackerUSERIDs) do
        for i, player in ipairs(AllPlayers) do
            if player.userid == ID then 
                SendRPCToClient(CLIENT_RPC.UpdateAccomplishment, player.userid, "fuelweaver_killed")
                break
            end
        end
    end 
end

The game is incorrectly using ipairs when looping through inst.attackerUSERIDS, when it should be pairs.
