Description of the problem.
- Suppose I have a blueprint pinned to my quickbar (the toolbar at the bottom of the screen). I can use the any normal/expected method to select the blueprint and put it in my hand. Good.
- Suppose I move this blueprint into a chest. The icon in my quickbar gets greyed out, to indicate that I won't be able to select it. This is the same behaviour as for any other item in the quickbar. Good.
- Now, instead of (ii.), suppose that I move the blueprint into a blueprint book which is in my inventory. Then...
- there is no visible change to the entry in my quickbar (the icon does not become greyed out),
- and furthermore, I cannot select the blueprint. This is the problem.
Steps to reproduce.
- Create a non-empty blueprint, as well as a blueprint book, and put both in your inventory.
- Click-and-drag the blueprint into one of the empty slots in your quickbar. Leave the book in your inventory.
- Open (right click) the book.
- Move (click-and-drag) the blueprint into the book. You can do this either by clicking on the blueprint's icon in your inventory, or also by clicking its icon in your quickbar.
