📄 Pattern Archive Update Changelog (1.20.1 Forge)

🇬🇧 English

New Features & Compatibilities

• Cross-Generation Compatibility (1.21.1 -> 1.20.1): Implemented backward compatibility for pattern archives generated in the newer 1.21.1 NeoForge version. You can now seamlessly import archives from 1.21.1 directly into the 1.20.1 environment.
• Cross-Mod Material Pruning: Added robust support for importing complex AE2 patterns containing non-item materials (like fluids or AppMek chemicals). If the target mod isn't installed on the current server, the system now safely replaces those unknown materials with empty placeholders to maintain pattern grid integrity instead of outright crashing or corrupting the entire pattern.
• Emergency Station Guard: Re-saving patterns containing complex generic types (fluids/chemicals) via the Emergency Station will no longer maliciously wipe out those custom generic items.

Fixes & Refactors

• Global Cloud Sharing (Ender Chest Mode): Completely refactored the data storage architecture of the Pattern Routing Hub. Previously, multiple players interacting with different hubs owned by the same player could trigger a bug that overwrote or wiped the stored memory. The system now functions like a global "Ender Chest"—your pattern data is stored safely in the cloud, completely immune to block destruction, and syncs in real-time across all your hubs.
• Critical Target Machine Recognition Fix: Fixed a severe routing loop vulnerability where placing Pattern Archive blocks adjacent to a Pattern Provider would cause them to be mistakenly recognized as valid processing machines.
• Unified Machine Detection: Streamlined the physical machine recognition logic. Both the Pattern Addresser and the routing engine now share a clean, unified whitelist/blacklist system, permanently preventing invalid neighbor blocks from being blindly injected into your pattern routes.

新特性与兼容性

• 跨世代向下兼容：对 1.21.1 NeoForge 的新兴数据结构进行了底层解包兼容，现在 1.20.1 也可以直接、无损地导入由 1.21.1 版本导出的样板存档了。
• 跨模组图纸智能净化：新增对含有非物品泛型材料（如流体或 AppMek 化学品）处理样板的安全迁移支持。若将图纸导入至未安装对应模组的服务器，系统会智能地将未知材料剪裁为空白占位符以维持 AE 矩阵的九宫格排版，而不再是粗暴地将整个样板作废丢弃或引发崩溃。
• 急救站无损防护：彻底解决了在急救站中重新绑定并保存图纸时，会导致其中的化学品等特殊非物品 NBT 节点被粉碎抹除的恶性问题。

修复与重构

• 全局云端共享与防丢机制修复（末影箱模式）：彻底重构了样板调配中枢的数据存储架构。如果未修复此问题，在不同地点放置多个中枢操作，且中枢都属于同一名玩家，此时多名玩家去操作这些中枢，可能会引发内存互相覆盖与清空 Bug。现在，中枢的数据机制已全面升级为类似“末影箱”的全局云端共享模式，无论方块本体如何损毁、如何多端同时添加和删除图纸，你的图纸数据都将绝对安全，且在你的所有中枢间实时互通。
• 方块误判与死锁漏洞修复：修复了在样板供应器旁放置本模组方块（如中枢、导入器等）时，会被系统错误当成“加工处理机器”并强行塞入处理样板的严重死锁 Bug。
• 统一机器探测规则：精简了略显臃肿的物理识别引擎。现在寻址仪扫描和物流分发将共享一套干练的黑白名单系统，再也不会把毫无关联的方块认作替罪羊机器了。
