Mystical World

- New entity: Silkworm! These do not spawn natively in the world. Instead, you may find silkworm eggs when breaking tall grass (like seeds), or breaking leaves (like saplings). Silkworm eggs have a 30% chance to spawn a silkworm, which will wobble around growing until it plops out a Silk Coccoon. You can drop leaves (as items) near the silkworm in order to speed up the process; in addition, the more leaves they eat, the higher the chance they will drop additional cocoons.
- New items: silk cocoon, silk thread & spindle: you can directly convert silk cocoons into silk thread (an alternative to string) in a somewhat lossy fashion, or you can craft a spindle and combine the cocoon with the spindle: you will gain considerably more return, although the spindle will take some damage.
- Materials have been greatly improved and conditional registration has been removed. Now, ore dictionary registration, ore spawning and recipes will be enabled or disabled instead.
- Fix #53: Repair items are now properly set for Amethyst, Copper and Silver tools.
- There is now an option to give the player (true by default) the Mystical World Patchouli Guide.
- Baked models have been replaced with standard Minecraft blockstate files, preventing future issues with Patchouli visualisations & Direwolf's Building Gadget.
- Mystical World entities no longer return "false" by default to "isAIDisabled".
- Patchouli: Amethyst, Copper and Silver entries are now conditionally displayed depending on whether or not they are enabled.
- Patchouli: All entity pages will display conditionally determined by whether or not the entity's spawn is enabled.
- It is no longer possible to disable Sprouts, as these entities are essential to Roots. They will be moved into Roots at a later date.
- Fix #57: ores now generation in dimensions specified in a whitelist in the config.
