Consistent errors in console

I've been getting these on occasion:

As far as I can tell, its just some random bug that I haven't been able to find the root cause for.  I put a simple patch into your code to prevent it, so i wanted to send it over just in case it might help others:

This is line 211-214:

        void OnLootSpawn(LootContainer container)
        {
            if (!loaded)
                return;

Right after 214, add:

            if (!container)
                return;

Clearly it's getting something that isn't a container that throws the error, and breaks out of the function, so its not populating whatever it is with look. This prevents it from filling the console with that error.
