Update & Fixes:

1. Fixed a performance issue where lightning devices consumed excessive resources.

2. Optimized low-level calculation code to reduce CPU usage.

3. Improved responsiveness when multiple pets participate in combat.
   (If each creature is very large, they may still fail to enter battle. This is an intended game design: creatures have mutual pushing logic. However, the underlying navigation code has been optimized to improve navigation responsiveness.)

4. Optimized the detection logic of zipline devices and added an option to exclude them from calculations. Once a device has been successfully linked, it can be set to no longer participate in subsequent zipline calculations (applies to newly constructed devices only).

5. Optimized the performance of backpack inventory slots.

6. Disabled line-of-sight obstruction checks for NPCs and companion creatures, while keeping them for wild monsters. Line-of-sight obstruction means targets behind obstacles are ignored (testing shows this significantly improves NPC and companion reaction speed).

Update Fixes:

1. Adjusted fixed-position bosses so they can still attack after leaving their territory, meaning the boss can be lured anywhere; it will return to its territory when it stops attacking.

2. Fixed issues with spoilage values of some dropped food.

3. Fixed the issue where Y-shaped tough wood was not respawning.
