Career not saving progress [bug]

Hi,

after playing today for three hours I suddenly got an error message after buying a new car in career mode. It said something about having some kind of file already and needing me to delete this file to free up space. Nothing more was specified. The game continued to work normally and I drove another 4 races and did a rivals event. After that I shut down the game by going to the XBox menu and quitting out of the game - so it was not in this kind of standby mode anymore. After starting again all my progress of this day is lost - something like 4 hours of playing.

Has anybody else experienced anything like it? I saw a video on YouTube, where the guy driving lost his whole save file with all loyalty rewards and had to start from the very beginning. Seems to be some serious bug affecting save files…

Just a quick update in case I wasn’t alone with this problem:
I’ve transferred all of the Forza 6 content from my external HDD to the internal XBox HDD and deleted all of the Forza 6 Demo content from my Xbox. The issue did not appear again so far. I’ve played through everything I had before losing my progress, bought a new car and made the next career race with it without problems. And I’ve restarted the game several times in between to test things. So it seems everything works ok right now.
