• Added FastAsyncWorldEdit support! If that plugin is installed on your server (It is a free plugin) then arenas can restore instantly and more accurately! This feature is supported from 1.7 till 1.16!
  
• In order to use this feature, make sure that FAWE is installed on your server and is running correctly, and make sure that Use-FastAsyncWorldEdit-When-Possible is set to true in config.yml in Skywars X (New option added). You should see a message that says 'Detected FAWE, it will be used when possible' in console when the Skywars plugin loads up, if not then try restarting or reloading.
  Then, for existing arenas, you have to select their region using SW WAND and simply write SW UPDATEREGION <Arena>. This will update the region as usual but if everything is setup correctly, it will also create a schematic of the arena and use it to rollback.
  For newly created arenas, this will automatically be done (A schematic will be made if possible)
  
  
• Checked 1.16 support

If this update fixes your issues with the old rollback system, then please show support as the reviews of the plugin went really badly since the last update where i changed the rollback code so that it supports Minecraft versions from 1.7 till 1.15 (Really hard to do). This implementation should allow more efficient and accurate rollback to be made using FAWE without my poor attempts at compatible rollback :L.
