Some No Man’s Sky players are having issues with their saved games after the latest update, but it looks like the problem has already been fixed. In the short term, however, be careful if you run into this bug.

“A whole bunch of people, including myself, have run into a bug in Next that prevents you from loading an existing save file. Instead of putting you back into the game at the point you saved, the game simply restarts you on a new planet with the ‘Initializing’ white screen,” a player wrote on Reddit.
