Honestly? I have played the full game on 360 (German version) and I really liked it. I had no bugs whatsoever and I don't even know what save game bug you are talking about. The only thing I felt was that the game became too easy at the end...level 34 and just maxed out whirlwind, health leach and regeneration. For the last hours I never need health potions or anything else (on normal) and the final fight was a bit refreshing since I once more needed potions (which I had zillions of).
Over all I felt the Xbox version was a really good game, with a nice story and - at least for me - bug free. I can imagine that when you train several more skills the handling might become a complicated, but I never used more skills than whirlwind and the fast storm attack, so it was fair enough. I am looking forward to the add on ;-)
