I could not save anything on my second play through. Change over to my twin, started a new game plus played for like 3 hours and could not save . Tried reset on Xbox one, did the LOOOONNNGGGG first mission again, (because you can ont save on priority missions, only to find out again, that I can not save. Had over 100 manual saves on my first play though. So I decided to delete and drop down to about 40 manual save files. Still nothing. So had to do the long first mission again, but decided to rebooot/reset again. Now I can save. Do not know what it is exactly, but be carful . Make sure you chech that your game is being saved, before wasting multiple hours of play for nothing.
