Always keep a set of back-up games. The v1.0 game, which I suspect is the one you've got, tends to corrupt the savegame, so you really do need to keep your back-up positions reasonably well up to date. That way, if things do go south, you won't have too much to replay.I remember once in Castle Kriegspire where I went into a corner to look at something, turned clockwise to come out of the corner (I can't remember exactly where, except that the scenery was brownish and it was only dimly lit), and the whole system crashed. Fortunately, I had a recent back-up, and out of sheer curiosity, went back to the same place and tried it again. The same thing happened. I tried it yet again, but this time I turned anticlockwise. No problem. I can't explain it — but I was able to finish the game!
