• Now worlds save icon's item additional data. Heads from HeadDatabase, custom banners will be saved correctly and it will add a little more appearance for your worlds.
• Search worlds by owner's name with LMB+SHIFT click.
• Added requirements section in config.yml, that has rules for changing world's name, description and ID. You can change required minimal amount of symbols, maximum amount of symbols for all, and pattern only for ID. So you can block cyrillic symbols, if you don't want.

requirements:
  # Copy and paste it in plugins/OpenCreative/config.yml
  world-name:
    min-length: 4
    max-length: 30
  world-description:
    min-length: 4
    max-length: 256
  world-custom-id:
    pattern: "^[a-zA-Zа-яА-Я0-9_]+$"
    min-length: 2
    max-length: 16

• Now you can hide Not Found Message, warnings, critical errors messages from console in config.yml

messages:
  # Add these fields into config.yml in messages section
  critical-errors: true # To hide, set false
  warnings: true # To hide, set false
  not-found: true # To hide, set false

• Now items will be checked by PersistentDataContainer, not by translation. You're able to make items names same and it will not cause problems.
• Fixed wrong spectator coloring (only for hide-from-tab: spectator)
• Fixed an issue with world border actions
• Fixed an issue with transferring world's ownership
• Fixed visual glitch with item when deleting world
