[1.2.5] another steam cloud victim

[nonno]

Hi.
I know the steam cloud saving is buggy, but I hope reporting the bugs will help fixing them.
In my case I was playing on my macbook and loaded the save on my linux desktop. At first everything seemed fine, but when I went to the global map it said something like "Generating level", like if I had never been there, and when the map appeared I saw that it forgot what I explored, it was black like new. The biggest problem is that I completed the quest to access Angolwen, but never actually went there, and now there is no portal to go there and I can't do the quest to make it appear again. The "apprentice" is still there, but I can't give him anything.
