A few save game related issues are outlined below.
What happened to my save games on the Xbox 360?
If you're not seeing your saves at all on the 360 version, please make sure you're logged in with the profile that you purchased the game on. If you are, please log out of your profile and then log back in, from within the game. Your saves should reappear after doing this.
I've already beaten Episodes 1 and 2 and when attempting to load Episode 3, it asks me to randomize my decisions. Are my choices lost?
No, they're not! This is slightly complicated, but there are a few things that can cause that to pop up.
If you quit out of either of the first two episodes during the end of the game or on the stats screen, before the credits roll, it won't successfully flag your game as having been completed. However, all of your choices are correctly saved and you can import them into Episode 3 without issue. You WILL get a prompt asking if you would like to randomize your choices for this episodes since your save game isn't technically flagged as being completed, but your choices ARE saved and WILL import into the new Episode. When it asks you if you want to randomize your choices, say YES. Again, this is misleading, but it WILL import your choices.
This issue can also pop up if you've ever used the Rewind feature to revisit certain portions of either of the previous Episodes. Once you've done that, your save will no longer be flagged as completed and will not update again until you've beaten the game and gotten to the credits screen. Your choices will still be saved, however, and saying yes to the random choices prompt when starting a new episode will actually import your choices correctly.
The long and short of this is that if you have successfully completed Episodes 1 and 2 at some point on your current save, and are getting the randomized choices prompt on Episode 3, you can safely ignore it. The only time it would actually randomize your choices is if you haven't actually played Episodes 1 and/or 2.
I know this is totally confusing, and we are looking into an update to make this process more clear. I definitely apologize for any confusion or frustration it's caused.
