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).
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.
