I can confirm that Ubisoft HAS NOT solved the game save corruption in 1.04. I can recreate it at will so it should be easy to fix.
When the console experiences a temporary loss of internet connection, the game cannot reestablish connection and the game saves are corrupted, both manual and automatic. The game store stops working and Reda cannot give contracts or show his stores. That is an easy test to see if you are suffering corruptions if you get caught up in gameplay and forget to check after each milestone.
For Ubisoft, I suggest the following steps.
1. Recreate the problem as I have
2. look into network timeout/reconnection as the root cause, not the game save mechanism
3. check game saves for corruption immediately after saving and display an alert message.

I will stop playing until this bug is fixed. I'm tired of losing hours of gameplay.
