So years ago, I got the 256 glitch. Back then, I was horrible at the game. I never pressed the x button. 256 was great for a time, until I wanted to have a sense of accomplishment. I started resetting single characters that I wanted to use and played like that for a while. Earlier this year, I reset my stats completely. It was the best thing I could have done.
In addition to that, I just ditched my xbox on Christmas and now I play on steam so I started over again.
Just start all over. Its not that bad.
P.S. 256s suck really bad. I had a level ~70 orange knight and played online with a 256 industrialist and level 26 necromancer. When we fought, I had more trouble with the necromancer.
