Optimize world



The optimize world screen is a game menu that is used to upgrade the level data of a world to the latest format. If the player optimizes a world, it is no longer compatible with previous versions of the game.

Options

 * Erase cached data
 * Cached data for the world is erased. This includes light levels and biomes, among other things.
 * Create backup and load
 * Creates an unoptimized backup of the world, and then proceeds with optimizing the original one.
 * I know what I'm doing!
 * Optimizes the world without creating a backup.
