Why are the achievements only tied to the character that you did the achievements with when the achievement rewards shared across all your character that you have?
It doesn’t working as intendent. Gearbox know about this. Next event will be working with all characters.
I can verify you get all the character skins when unlocking the 3rd reward. If anyone is curious. I finished all the challenges today so hopefully next time they do a free event this is fixed so I can swap around character once ai get tired of grinding some of the longer challanges.
