Well I have to agree with Killua for the glitches part. I never saw that kind of glitches in the game. I mean so bad anyway.
Not saying there weren't any as well for example one was that the woman blacksmith (don't remember the name of the town) that her blacksmith was next to the gate and next to your house always stayed in the same spot day and night always there. Or when i had a couple of times corrupted saves. But other than that I didn't have any other major glitch.
