This is how I brushed it, and there will be no bugs. The actual test time was adjusted back one month. After the modification, it was fine. I still received the box and found things while exploring.

It's so cool, but it won't be interesting after the time method.

There is another way. You can get stuck when you exit and re-enter when collecting the box, but you need hand speed. It is easier to get stuck if you have physical buttons.
