  • Fix NPE when Spigot late-bind option is enabled & improve injection logic

This PR fixes a NullPointerException that occurred when the Spigot "late-bind" option was enabled on servers prior to 1.14.4.

Changes:

  • Changed injection priority: The plugin now attempts to register the Paper TickEndEvent first. It only falls back to NMS reflection if the Paper API is unavailable.
  • Added a null check for the server connection instance to prevent the NPE during reflection injection.
  • Added specific error logging: If injection fails on legacy servers (< 1.14.4), the plugin now reflectively checks spigot.yml settings to explicitly warn the user if late-bind is the cause.
  • Refactored reflection logic to use ReflectionUtils for better safety and code cleanliness. - by uRyanxD (5f02ccc)
  • Bump PE - by Axionize (92d06e4)
