Changelog

  • update to 1.21.9 and 1.21.10
  • The keepJigsaw, maxChunkStatus, and saveChunks gamerules duplicate the new debug flags. For now they are still present as it is easier to change a gamerule than a debug flag. If/when a different mod makes runtime modification of those possible, the gamerule will be removed from this mod.
