Posting research here for personal reference

The issue here is a mix of CreativeTabs being constantly reloaded (Probably not us? Thinking its Owolib) and the fact that when we do creative tab stuff we run a registry look for every block item. We MIGHT be able to just throw a reference to the block item in the class, but the way of doing so that Im thinking is a horrible idea.
