No Aggro error code

[Tigger_Fan_]

Okay, so I'm trying to make a battlefield scavenger-like character, and have it so mobs won't aggro onto him. This is the code I have in modmain.lua so far:

-- wulchur is the character name

local function PassiveUntilAttack(wulchur)
    if wulchur.inst:HasTag("shadow") then
        return
    end
    local _SetRetargetFunction = wulchur.SetRetargetFunction
    wulchur.SetRetargetFunction = function(wulchur, period, fn)
        if fn then
            local _fn = fn
            fn = function(...)
                local _target = _fn(...)
                if _target and _target.prefab == "wulchur" then
                    return
                end
                return _target
            end
        end
        return _SetRetargetFunction(wulchur, period, fn)
    end
end

Every time I try to run it, I get:

[00:02:48]: Orphaned unnamed resource. This resource must have used Add( resource ) to insert itself into the manager. 
[00:02:49]: CurlRequestManager::ClientThread::Main() complete

What needs to be fixed?

 

EDIT: Oh ya, and he's in a multi character mod pack. Might make a difference.
