Engine Error due to blueprints

I was creating a very large castle in the design editor. I had saved the blueprint for every level completed. When I had finnished and was about to save the blue print for the last time the game froze and crashed. When loaded my recent saved game I got this Engine Error report and all of my saved blueprints were gone. This error displays every time I load a saved game, no matter when I saved. Im also unable to save any new blueprints I’ve created.

Steps to reproduce:

  1. Build very elaborate cosntructions?
  2. Save blueprint and wait for crash
  3. Load game
