Those particular pages may either have been pruned, or weren't created until 6 months ago. But other pages like the Apocalypse event go back to game launch.
But that's a shame that there doesn't appear to be a record of old limit break costs anymore. I just awakened to 3-star now. I ended up running out of Dragon Fangs, which luckily are fairly easy to farm. I also used a large number of the SR LB books. We might need someone to actually document the costs. I think a total of 15 Dragon Fangs, 15 SR books, and 10 SSR books are required, but those numbers should be verified.
