Hello, please help.
~ In my menu on the clicker, the gist is this, the player can buy a clicker by pressing the left key, or improve it by pressing the right key, but when improving, the item just does not appear.
~ Second problem : [refresh] does not help, the item can be bought a second time, and only then it disappears. This is not related to the first problem, but it is also a problem.
~ All menus on 1.16.5 purpur and 1.12.2 reaper open with some huge delay.
