Optimizations:
1. Added a delete save button.
2. Closing from outside the furnace will spawn materials.
3. Opening and closing the map will interrupt movement.
4. Increased the maximum crafting quantity to 999.
5. A composite material in a chest was mistakenly set as a blueprint.
6. Fixed an issue with NPCs' weapon selection for gathering.
I've already documented some features, but they require complex testing to fully update. For example, I've designed solutions for switching running modes and detailed NPC gathering, but developing these will take some time.
The above are what I consider safe additions, so they are prioritized for updates. If you find any issues, feel free to let me know.
