It looks like Google hit another directory. The BOTW.org homepage is no longer cached in Google. If you search site:botw , you will also so see a number of categories not cached as well. If you search using site:submit site, you will find a number of supplemental results as well.
Looks like a penalty of some sort. I can only guess that it is related to duplicate content. Possibly empty categories? or allowing Google to index dupe pages like Add URL?
