GrandSeas v0.1.5-BETA

This update brings highly-requested features for island management and introduces critical bug fixes that drastically improve server stability and security.

✨ New Features

🤝 Co-op Mode (Temporary Access)

Tired of trusting players permanently just to help you build? You can now grant temporary co-op access!

• /is coop add <player> [minutes] — Grant temporary build access (default is 60 minutes).
• /is coop remove <player> — Revoke access immediately.
• /is coop list — View all active co-op sessions and their remaining time.
• Note: Co-op players cannot modify island settings, use GUI menus, or upgrade the island. They only have basic build/interact permissions. Co-op sessions are saved across server restarts.

🛡️ Admin Management & Moderation

Expanded the /isadmin command to give server owners full control over islands.

• /isadmin list [page] — View a paginated leaderboard of all islands, their owners, and points.
• /isadmin backup <player> — Instantly create a secure YAML backup of an island's data directly to plugins/GrandSeas/backups/.
• /isadmin bypass — Toggle an Admin Bypass Mode allowing you to freely build, break, and interact on any island. (Auto-disables on server restart for security).
• /isadmin audit <player> — View a 50-entry Audit Log for any island. Tracks who placed/broke blocks, who received co-op access, and when sessions expired. (Actions by the island owner are ignored to prevent spam).

🐛 Bug Fixes & Optimizations

• [CRITICAL] Point Calculation Race Condition: Fixed an exploit/lag source where multiple players reloading points (/is reload) simultaneously could cause server freezes or data corruption. Calculations are now locked per-island using atomic thread-safety.
• [CRITICAL] PointStorageGUI Dupe: Fixed a severe item duplication exploit within the Point Storage GUI.
• [HIGH] Server Crash (NPE): Fixed a NullPointerException that occurred when checking a player's location against an island whose chunks weren't fully loaded yet.
• [HIGH] Acid Snow Logic: Fixed a weather detection bug. The plugin now accurately checks biome temperature (< 0.15) to detect snow instead of rain. If acid-snow-damage is disabled in the config, players will no longer randomly take damage in cold biomes.
• [OPTIMIZATION] Island Creation Logic: Hardened the island creation process with strict try-finally blocks to ensure players never get "stuck" in the creation queue if an error occurs during schematic pasting.
