For my first career mode fighter I made a lightweight. Went through the career and retired him. Then I went to start a new career and make a new fighter and all it would let me make is a welterweight. Checked out the regular "create a fighter" and I could select different weights in there, but it won't let me change weight class in career mode. Any ideas?? Haven't been able to play online since I'm changing service providers, but I don't see how that would make this happen.
