Requirements: This method requires. FastAsyncWorldEdit to be installed.
If you enable Arena Regeneration, the arena will return to its initial state after each match. Any changes players made, such as placing or breaking blocks, explosions, and more, will be undone. For the regeneration to function correctly, it's essential to properly define both the Universal Region and the Battle Region. Failing to do so may cause the regeneration to not work as expected.
Arena Regeneration relies on WorldEdit to function properly. However, we strongly recommend using FAWE (Fast Async WorldEdit) instead of the standard WorldEdit, as FAWE is significantly more lightweight and optimized, reducing the chance of lag during arena regeneration. This ensures a smoother experience for your server.
