Bayonne, can you please answer this question:

Will the new recipes and yields for items such as Yarn, Lumber, and Leather be in addition to or a complete replacement of the current recipes?

For example, will 2 Moko Grass = 12 Hempen Yarn *or* 1 Hempen yarn (different synths) or will it become only the later?

This matters a great deal to players right now because if so we will want to convert all our raw materials before the patch goes live.
