I've completed several challenges, but when I went to get my reward for the last one I did, ALL of the ones I've completed are now marked as incomplete. It still shows I have done each step per completed challenge, but it says I 0/x again, as if I didn't do any of the steps.
I can't believe this bug still hasn't been fixed.
The challenges haven't been reset, it just shows completion incorrectly, but it's an incredibly irritating bug.
