After the preliminary adventure, give me a prop, but it won't work
Using the F12 key, the system opens the props by default, selects the items, and then uses them. The same is true of ship vouchers sent back from schools
Double click the props, select the props, and then use a button
On the right there is a "use props" command, open, click on the memorial ceremony, and then click the window, the bottom right corner of the confirmation.
