I was playing through the prologue for the first time and found an issue which I came to the forums to look into. While here my game timed out and closed the game (seems like a very short timer). I logged back in and I have gone back to the beginning of the prologue. This is an issue that was reported back in November of last year and still has not been resolved.
There are two issues here, one, when the game times out, why close the game? Really it should send you back to the character selection screen, not close the game completely.
Second, progress through the prologue should be saved.
