DimensionAccess 1.3 — Anti-Bypass Update (Paper 1.21.8)
Major rewrite focused on security and modern Paper compatibility.

Players can no longer enter restricted dimensions using alternative teleport methods.

Fixed bypasses

• /tp, /teleport
  
  
• EssentialsX /home, /back, /spawn
  
  
• Warps & RTP plugins
  
  
• Plugin-forced teleports
  
  
• Joining or respawning inside restricted dimensions
  

If a player somehow appears inside a blocked dimension, they are automatically moved to a safe spawn.

Improvements

• Checks target world before teleport
  
  
• No message spam while teleporting inside same dimension
  
  
• Better performance & stability
  
  
• Fully compatible with Paper 1.21.8
  

Players without permission will never be able to stay inside the restricted dimension.
