Sorry for the short post. I don't have much to say except my save file got corrupted (my best guess), and when I loaded it I started at the beginning of the game with nothing. I thought this is a problem I might face more often with cartridges and battery saves, but this was on the Xbox 360 with its hard drive. I read that this version actually has save states and it's recommended to use them over the original save feature.
So, last night was spent grinding back up and completing the quest up to the point I did the previous night. I didn't spend quite as much time grinding, so I'm short a sword and armor I bought for Odin previously. I might spend some time to grind those out tomorrow night, but I was disappointed and just wanted to get back to where I was without going further story-wise.
