Some background: a couple months ago I experienced the all-too-common game save corruption bug on my PC version of TWD game about 20 hours into it. My save files are still there, but the game does not recognize them, and no amount of fiddling with timestamps / prefs.prop files / restore points has restored them. I have reached out to TTG support in hopes of a bug fix, including this post (http://www.telltalegames.com/forums/showthread.php?t=41801) requesting some sort of game save generation tool for those of us that have been affected by this bug, assuming it couldn't actually be fixed. I received a copy-pasted response on the thread (verified it was copy pasted by searching the forums with the text from his response) that gave no insight into the bug and offered no solution or timeframe for a fix.
Since TTG seems to take no interest in responding seriously to these bugs or fixing them in any way, I too have filed a complaint with the BBB. I suggest anyone who has had these issues, or others that have gone unanswered, file a complaint as well. It took a few minutes, just give some personal information and a couple paragraphs detailing what's up.
