Bug:
Fix the pathfinding bug that could easily cause the game to crash.
Fix the bug that the warehouse prefab model can also reduce the total capcity when building is cancelled.
Adjustment:
Optimize the pathfinding algorithm.
The fourth item that can be sold in the first level is changed from stone to steamed bread.
The drop-down menu for selling items has been deleted, so as not to cause players to misunderstand.
Automatically pause when the menu is called up.
