Release 8.0.27 — New day, new problems

This update focuses on robot navigation and automation, with smarter mining, more reliable docking and fixes for several long-standing edge cases. It also addresses crashes involving the Flood Gate, Guide Book and certain modded setups, and improves Blueprint safety.

Important:

This update fixes a critical exploit that could allow players to place blocks without consuming the required resources.

All server owners are strongly advised to update BCCE immediately.

Changes:

• Improved Miner Robots. They now look for the nearest reachable ore based on the actual route, then try to finish the same connected vein before moving to another deposit. Regular and deepslate variants of the same ore are treated as one vein, and mining progress is remembered after reloads.
• Improved robot navigation and docking. Robots can find longer, winding routes back to their stations, recalculate paths when obstacles change and wait for occupied or temporarily unavailable docks instead of immediately abandoning the journey. Gate-controlled station returns also remain active until the command is turned off, and short loading interruptions no longer break station links.
• Changed Blueprint and Template size limits to prevent extremely large designs from exhausting memory. Saved construction areas are now limited to 512 blocks per dimension and 2,097,152 blocks in total.
• Changed Blueprint copying so saved designs no longer restore stored items, fluids, energy or ownership data from machines. This prevents copied structures from creating free resources or inheriting another player's machine ownership.

Fixes:

• Fixed the Flood Gate crashing when placing water or other fluids.
• Fixed Planter Robots ignoring saplings and crop seeds on Minecraft 1.21.11 and 26.x.
• Fixed Guide Book crashes caused by unsupported recipes from other mods, including Applied Energistics 2. Incompatible recipe entries are now skipped without crashing world loading or the entire Guide Book.
• Fixed robots breaking blocks or using tools twice while checking permissions. Attack Robots no longer chase targets outside their assigned work area, and failed Stripes Pipe interactions are no longer treated as successful actions.
• Fixed fluid-carrying robots ignoring changed fluid filters or incorrectly accessing protected tanks and pipes during pumping, loading and unloading.
• Fixed Delivery Robots keeping old item requests after a job ends or is interrupted. Searching for requested items is also more efficient in large modpacks.
• Fixed the Requester treating different variants of the same item as interchangeable. Requests now respect item properties such as stored charge, while explicitly configured Item List filters still allow broader matching.
• Fixed Builders accepting altered Blueprints that could place entities outside the planned area or bypass material and protection checks. Saving large Blueprints on Windows is also more reliable.
• Fixed the Tank GUI showing fluid in an empty tank or displaying incorrect fluid levels.
• Fixed Jade showing the generic name "Robot" instead of the robot's actual type.
