So I Installed 1.09, heard about the issue and didn't play, I stayed off the game. Heard about 1.10, it prompted me to download but I paused it at 1%. Today (1.11), I wouldn't get the prompt for 1.11 cause 1.10 had to finish first (or it had to say that Injustice 2 is 'Ready to Start') so I let 1.10 download to 80% or so until injustice 2 could start then paused 1.10 again, then I booted it up and got the prompt for 1.11. So I Installed that. I then loaded up the game and saw nothing was lost: source crystals, shaders, gear, credits, Legendary Multiverse progress and all.
