⚙️ Compatibility Notes
Grim Users

• Ensure you’re using the latest version.
• Enable the disable-pong-canceling option in your configuration.

ExploitFixer Users

• Update to the latest version.
• Ensure Ping/Pong and Window Confirmation packets are whitelisted and not canceled.

Failing to do so may result in players being kicked for invalid or out-of-order confirmation packets.
⚠️ Reminder
Vulcan is built for vanilla clients and expects vanilla packet behavior.
Modified clients, custom mods, or plugins that alter or cancel packets may cause unexpected issues or false kicks.
These setups are not officially supported and may interfere with normal operation.
