I purchased the physical copy of outer world's for my ps4 and played without updating to any patches till I found I couldn't access any of my saves after going on the mission to meet Elli's parents and skipping the hope. After trying to load a save, my game would "freeze" on the title screen with no available options, music still running and never go to an actual loading screen. I have tried skipping Elli's quest, uninstalling and reinstalling the game, moving my save files to usb storage and all of my "inaccessible" saves are all around 9 mb. I saw there were some people on the forum with similar sounding problems, so yesterday I finally updated the game to the most recent patch (1.3?) and now receive the error code e-b51d0002 when trying to access the files, instead of the "glitch" where the game would crash.
I have started a new game to see if there is any hope, but it does suck losing so many invested hours and worrying about encountering this problem ahead.
