@IxamTheMerciless Eitherway, it doesn't make sense for some to get all the reward items when others did not, (besides the ones who didn't participate in the event).
This to me sounds like an issue on EA/Respawn's end, and I hope they would properly award the players who participated in the challenges.
For me, I had every single challenge finished besides the bugged OG one prior to the removal of that challenge. When I had logged in an hour after the patch went live, I was awarded the Defiance pack and the badge.
Note: This is why I had assumed everyone had gotten the reward. I do apologize that this wasn't the case for everyone.
Edited: Looking back at the screenshots from when the challenge was in the game and at the one I took when I was awarded the pack, I've realized that I had misread it.
The Defiance Pack is earned once you finish week 2. The normal Apex Pack from finishing the OG challenge was indeed removed from being earned.
It also looks like Respawn had removed the OG challenge from week #1 as well, so if you didn't finish week 1's OG challenge, you might be missing that reward too.
No idea why they didn't just auto complete the challenge for everyone who couldn't get it completed, (which would of given them the reward items in the process).
That would of made more sense and been a bit more fair then to remove rewards that should of been earnable.
