VeinSpread

This is a massive update for VeinSpread that completely overhauls how veins grow, making them look and feel like living, organic roots.

✨ New Features

• Living Roots (Random Ticks): Veins no longer grow in robotic, synchronized steps. They now spread organically via a configurable chance per tick, just like natural crops.
• 3D Thickening: Veins don't just draw thin lines anymore. They now naturally fill gaps and thicken closer to the catalyst, creating solid, volumetric masses at the center while leaving thin tendrils at the edges.
• Hard Block Limit: Added max-blocks-per-catalyst to prevent infinite growth and protect your server's TPS. Set it to -1 to remove the limit entirely.
• Full WorldGuard Support: The plugin now properly fires BlockSpreadEvent. If a block is inside a protected region, the vein will not break it.
• Smart Destruction Tracking: If a player breaks a vein, a Creeper explodes, or WorldEdit removes blocks, the plugin instantly updates its data, decreases the block count, and allows the vein to regrow.

🛠️ Performance & Bug Fixes

• Massive Memory Leak Fixes: Completely rewrote memory management for tracking placed blocks. Removed redundant lists and fixed memory leaks that occurred when chunks unloaded or blocks were destroyed.
• Instant Startup: Removed heavy 3D cube scanning on server start. Placed blocks are now saved directly to veins.json and load instantly.
• No More Data Races: Fixed ConcurrentModificationException errors during auto-saving by implementing deep snapshots of the data.
• Optimized Direction Picking: Removed unnecessary object allocation when calculating branch directions, reducing Garbage Collector load.

⚠️ Important Note for Upgrading

The default values in config.yml have been heavily tweaked (e.g., growth-chance is now 0.02 and thicken-per-tick is 5) to ensure smooth performance on servers. Please delete your old config.yml to generate the new one, or manually add the new options.
