I have experienced this error several times and I recently experienced it again. I am tired of getting all of my Equipment, perks, and getting all my weapons to legendary and pack-a-punch three to experience this error. I lose all of my aetherium crystals and all of my progress on the levels. I have already scanned my files with nothing being repaired and my friends are experiencing this error as well. They have scanned their files with the same results as myself.
