I noticed you did some cleanup on how items get logged. When I have a stack of multiple items (e.g. <ore:ingotCopper> * 3, it logs as such: minetweaker.api.item.IngredientStack@65d292c.

This is a very minor issue of course, mainly just a note for myself so I can submit a pull request when I have some time.

This isn't an issue for us, it is more an issue for minetweaker.
