Okay - CPH says - To download the rest of the update. You may not have explicitly chose to download the update but the X1 will download stuff in the background automatically, so sounds like you have part of the update and need the rest. Okay try this. Finish out your level with the current characters. Then start a new level with a different Lifeline character and see if it jogs the system into getting them all corrected. Sadly what happened was that CU3 updated in parts and not as a whole so your files got corrupted. I apologize for that. It wasn't the best execution and we learned a lot from that process.
