[0.18.45] Crash when putting a blueprint in blueprint library

Multiplayer game (1 server headless on linux + 2 players on windows), no mods.

I had a blueprint book on my library, and a blueprint freshly created (copied from ground). When i tried to put the new blueprint into the book, i had the book in my hand and the blueprint in the library and game crashed. Last save attached, although the crash occurred 30 mins after.

When restarting the server, i lost my book of blueprints but the "new" plan was in my library.

I didn't see this crash already reported, but maybe i missed it.

Error Blueprint.cpp:314: Loading blueprint will desync on loading since it has empty contents but non-empty preview data.PreviewIcons: {{name=stone-furnace}, {name=transport-belt}}, description: "", absoluteSnapping: false, snapToGrid: empty

Here's my old book of blueprint, doing same makes game crash systematically

Note that the book of blueprint contains blueprints NOT from vanilla. The game was vanilla, still.
