I'm surprized that the blueprint library cannot contain the same blueprint multiple times, even if they are in different folder/books. It worked fine before.

What happens (how to reproduce)

• Load a game.
• Create a new blueprint.
  Lets say we named it A.
• Insert the blueprint multiple time in the personal library (in different folders - one can be in the root folder).
  Let's say we have now a A in SteelWolf300, SteelWolf300/Book1 and SteelWolf300/Book2.
• Until now, every A added is accessible.
• Quit current game (with or without saving).
• Load a game (can be the same save).
• Only one A remains in the library.
  It is located in SteelWolf300/Book1 (It is the first one lexicographically - the root seems to be considered after every folder).

I have not tested the "Shared blueprints" part. I can only say that this behavior does not happen with Game blueprints.

How I discovered this bug

I have a blueprint named "~Made by SteelWolf300", which I used to put in every book with personal original content, in case an other player copy it - yes I'm proud of my work .

I realized recently thas almost every instance of this blueprint has disappeared.
I added the blueprint again and again, but every time I load an other game, the changes are lost.

After some investigations and testing, I came to the conclusion I exposed in the first part.

Thanks, fixed in 0.15.34.
