It seems the xml save will create corrupted savegames if the size of the map is fairly large.
I can not yet give further details to this but I will attach a usual compresses save that will be corrupted when saved as xml save.
Edit: Nevermind, it seems I cannot reproduce it again. There were three corrupted xml saves in a row but now It worked and I could not reproduce a corrupted save although I tried to many times.
