No save file required. Deimus told me that this is a bug in the game, it will be fixed in the next beta version of the game.
Sorry, I did see this post earlier. Ok, thanks. It sucks that am soft locked until then, but I will make do
In such cases, autosaves (last 3 game days) and when you periodically create saves yourself are useful. The latter is useful in all jRPGs.
