It took longer than usual to load the game, and when the load was completed, the entire screen was displayed in purple and the trees and cacti were all displayed in black. After a while, it returned to the original display, but when the iron pickaxe kept the name display and the inventory was unchanged, it became an enchanted bottle. It was in the state of the enchanted bottle even if I changed it to another object and changed it to the iron pickaxe again. After I quit the game once and restarted it, I returned, but if it happens many times, the game will not progress, so please correct it.
