Enchanting

[daniel0916]

LO1ZB has a good idea.
He will check the bookshelves not on every enchanting.
He will check the bookshelves when a enchantment table will be placed (and save).
He will check the bookshelves when a bookshelves will be mined in the area of a enchantment table (and save).
He will check the bookshelves when a bookshelves will be placed in the area of a enchantment table (and save).

Is this better than check every enchanting how many bookshelves are around the enchantment table?
