Weird.
So you've done all you're week 1 and 2 challenges... So you should have the style.
Idk honestly, just gonna ping u/EmptyTux so he might see this and try to help you somehow.
Can you provide a screenshot of what you see when trying to select the Crimson version of Jennifer Walters /u/LSD2110 , just so we can see what you're seeing?
Is she locked in your Battle Pass screen (on right-most tab past Wolverine) or are the challenges complete and she appears 'unlocked' but you cannot select the Edit style in your Locker?
Thanks!
