RZero

🌐 Multiplayer Support

• Added support for co-op play. The state of offline players is correctly saved and restored.

🧬 Natural Spawn Determinism

• Mob Generation: Rewrote the natural spawning logic for animals and monsters. Spawning no longer depends on how players navigated the world. A mob that appeared on day 5 before death will appear again in the same chunk with the same UUID after a rollback.
• Unloaded Chunk Catch-up: If a player takes a different route after a rollback, unloaded chunks track missed time. Upon loading, the mod automatically simulates the missed epochs and spawns the animals that were supposed to appear.
• Independent Mob Cap: Instead of the vanilla mob cap, a local fixed limit within a 3x3 chunk radius is used, ensuring spawning reproducibility.

🛠️ Bug Fixes & Stability

• Entity ID Collisions: Fixed a bug where new mobs could receive the internal IDs of restored mobs, resulting in their deletion or visual invisibility.
• Block Events Clearance: Prevented delayed events, such as piston movement or flowing water, that started before the rollback from carrying over into the restored past.
• Memory Leak Prevention: Added automatic eviction of old mob behavior data from RAM to prevent leaks during long play sessions.
• Refactoring & Dependencies: The internal architecture of the mod was split into modular subsystems. Updated loaders to the latest versions: NeoForge 21.1.247, Fabric Loader 0.19.0.
