Great game with a serious bug

I have really enjoyed the graphics of the game and the way it makes you think to solve interesting and sometimes funny puzzles. But although I have saved the game several times it has a serious issue that doesn’t let me load the game from the part I have saved last time. My macbook is a good and updated system: Retina, 2.6 Hz, OS X 10.10.3, so I don’t think the issue is about my computer. In any case after starting from the beginning each time I wanted to play the rest of the game, I gave up on playing it, since I have to do all the previous parts before being able to play the new part. As another reviewer has mentioned playing previous parts again can be of course faster than the first time you try to solve those puzzles, but it is a serious bug and takes its own time, and I think that can stop you from playing the whole game from the beginning each time.
