Stability update!

Now, can open most of the time without breaking!

Known bugs: Custom items (e.g. blah:meh) will not render if they are using the correct item model, but it renders on other items if set. (item with id blah:meh will not render if model is blah:meh, but all other items can render if model is blah:meh, and blah:meh can render model of any other item. Unknown cause.)
