I have been playing it for a day or so and found out that if you for example have a lot of bone meal and you make bone blocks, there is a section at the left of the screen where you can select the thing you want to craft. After some time, it just stops working and you cannot move anything or click on anything in the inventory or the search bar so I need to go out of the inventory and then in again so I get it to work. Sorry for the grammar, I cannot type today.
