Please read the update log carefully

• Updated the API to 1.13! You can now use 1.13+ items in your servers! Older versions till 1.7.9 are still supported but obviously they can't use those items
  
• Due to the removal of IDS in 1.13 API you have to recreate all your arenas as they were stored using IDS (Delete arenas folder)
  
• Block behind sign is now back updating!
  
• Reduced console messages on startup
  
• Removed winners map

* Please be reminded that you DO NOT HAVE TO upgrade to this version! You can stay on 4.1 and not go through the hassle of recreating arenas. But i will not be able to help you if you find any bugs in 4.1 or below. You have a lot of time to upgrade to 4.2. This change is desperately needed as IDS are no longer a thing

* This version is experimental and can be reverted. If you find any bugs please report to me i will see if i can fix them!
