Changing rituals or Altar recipes breaks the book by throwing an error in the opening GUI saying "error loading [insert ritual]" for example, changing the Ancient sapling recipe. or changing the Sugar cane to sugar recipe.

When trying to access certain entries or multiblocks crashes to main menu throwing a patchouli error.

Are you giving the new recipes the same names as the old ones?

(I just added a little info about recipe names and their importance to the info file, by the way.)
