I forgot to save my game before finishing 0.4 and I'm having to restart while playing 0.5, is there any way to completely skip forward to the newest part of the story?
You may be able to check the autosaves page it should have some there. It's the A on the left of the numbers in the load screen.
Otherwise you can right click the skip button at the bottom and hit "skip to next choice" and it will go quickly. Just make sure not to skip past dalias attack cue in ch1.
