Hub Routing Overhaul
This update fully rewrites and stabilizes the hub routing and fallback system.
Focus: reliability, smooth player flow, and clean messaging.

✨ Improvements
Smart Hub Selection

• Added intelligent hub selection based on player count
  
  
• Automatically routes players to the best available hub
  
  
• Supports soft/hard limits for load balancing
  

Reliable Fallback System

• Players are now correctly routed when any server goes down
  
  
• Behavior:
  
  • → Sends to available hub if one exists
    
    
  • → Sends to fallback only if no hubs are online
    
• Works globally across all servers
  

Continuous Hub Detection

• Fallback server now continuously searches for available hubs
  
  
• Players are automatically moved when a hub becomes available
  
  
• No manual reconnect needed
  

Connection Throttling

• Added randomized delays (100–500ms) for reconnect attempts
  
  
• Added staggered delays (200–1000ms) when many players are waiting
  
  
• Prevents hub flooding during mass reconnects
  

Messaging System

• All routing messages now come from messages.yml
  
  
• Clean and consistent user experience
  

Added messages:

• routing.searching → shown when player enters fallback
  
  
• routing.found → shown when a hub is found
  
  
• Removed redundant message spam from scheduler
  

Internal Changes

• Reworked LimboRouterListener for better tracking and cleanup
  
  
• Improved FallbackListener routing logic
  
  
• Added HubUtil#getBestAvailableHub() for smart selection
  
  
• Added HubUtil#isHub() helper method
  
  
• Fixed initial join handling via ServerConnectBlockerListener
  
  
• Made sendMessage() accessible across components
  

Fixes

• Fixed players not being routed correctly when servers go down
  
  
• Fixed fallback not connecting when hubs are unavailable
  
  
• Fixed hub detection inconsistencies
  
  
• Fixed message duplication issues
  
  
• Fixed improper routing during initial join
  

Result

• Stable server switching
  
  
• Correct fallback behavior
  
  
• Smooth recovery from server downtime
  
  
• Clean, controlled messaging
  
  
• Scalable for large player counts
  

⬇️ Update Notes

• No config changes required
  
  
• Fully backward compatible
