There was an issue with our Codex plugin interfering with another plugin on Spigot named Codex. This update renames our Codex plugin to CodexCore. If you are using any of our plugins that require this plugin you will need to update for this version to work!
-Update to 1.21.1
-Rename to CodexCore (read message above)
-Fix skull decoding in 1.21
-Fix some issues with Leaf... there are still more
-Fixed this issue:
