CraftersLogin v1.6 — Critical Premium Auto-Login System - Fully Functional

🔧 Fixed

• Premium auto-login was not working correctly when switching servers or reconnecting because the premium status was not being validated early enough in the connection process
• Already registered premium players were incorrectly rejected because the system was not recognizing their existing registration during the UUID validation process
• The auto-login system was generating false positives because it was not properly distinguishing between new and existing registered players during UUID mismatch checks
• Database error when updating accounts because SQL queries were still referencing columns that had been removed when the ban system was deleted
• The premium player cache was throwing internal errors because the implementation was using a view of the key set that became invalid when the underlying map was modified
• Premium players were not being correctly forced into online mode because the authentication listener was not running at the right priority level in the event chain
• Internal message communication between the proxy and backend servers was failing because the listener was expecting messages from the wrong source type
• A player's premium status was not being saved to the correct database table because the enable and disable methods were using different tables inconsistently
• The console was generating excessive spam because informational messages were being logged at the wrong level
• Expired premium accounts or players who used /premium before their subscription ended were not being handled because there was no way to disable premium mode once enabled

➕ Added

• Early premium validation system at the moment the player attempts to connect, before entering the server
• In-memory cache manager for premium players, improving verification performance
• Database support on the proxy side for storing premium player data (H2 and MySQL)
• Configurable message for when a premium player fails automatic authentication
• Using /premium now kicks the player so they can reconnect and apply auto-login correctly
• Changing another player's password as an admin now automatically kicks that player for security

🔄 Changed

• H2 is now the default database, MySQL is now optional
• All system messages were moved to configuration files, none are hardcoded anymore
• /cl ban and /cl unban subcommands were completely removed
• The spawn command was restructured with new subcommands: setspawnregister, setspawnlogin and setspawn
• The ban system was fully removed from the database for better compatibility and a lighter JAR size
