LightReboot

LightReboot is a Paper plugin for safe, configurable server restarts. It gives staff a clean reboot command, countdown warnings, optional schedules, and a controlled shutdown flow that saves data before calling Bukkit.shutdown().

• Broadcast, title, actionbar, and bossbar countdown messages

• Safe duplicate-countdown prevention
• Config validation with clean console warnings
• Optional plugin-disable list before shutdown
• Optional PlaceholderAPI support in player messages
