So with the newest update and DLC installed on my xbox one I started playing and noticed that for some reason my badass rank had been set to 0 but my progress on badass challenges had stayed. And that’s not it, my cosmetics for all characters are gone as well. I was wondering if there was a way to fix this or will I just have to live with it?
Sounds to me like your profile data may have gotten corrupted. I could be wrong so don’t take my world. I would put in a support ticket to https://support.2k.com/hc/en-us/sections/200300113-Borderlands-2
Depending on your platform you may have backups to your saves stored in the cloud. I would say flag this post and have it moved to the tech support category of your given platform that way others who know your platform can offer advice.
