Found an issue with blueprints not dropping to the toolbar when quick-dropping (Q) if another blueprint is already on the toolbar.

This somewhat makes sense as items will not drop to the toolbar automatically if another item of that type is already present on the toolbar, however seeing as blueprints are technically different I feel that they should behave as being different items essentially.

Refer to the below gif to see what I mean. Note that this behavior is also seen with blueprint books.

Might be a bug, might not be a bug, thought it worth reporting anyway.

That's by design and how everything works with the quickbar.

Items will never go to the quickbar unless:

• It originated from the quickbar
• There isn't already one of that item in the quickbar at full stack
• There is a filtered slot for that item in the quickbar
• You manually put it there

You can put it in the quickbar or filter the quickbar and it stays there.
