Rising to the Challenge objective bug

Hello Miiessie ,

This is probably not a bug, you can only complete 3 objectives from this group. You probably completed the other 3. So the 4th won't be redeemable.

That doesn't make sense 

I had the same problem. It's just glitches (claim all) and it will redeem.

Thank you for your answer. I was just going here to mention that haha. Guess more people will search for this answer, so thanks a lot m8
