I never received my rewards for the competition!!!

Hi @reBootPoL and no worries, even if your game crashed whilst loading, the rewards will be granted on the server-side correctly.

2012 Credits
17 Cmdr. Jackson cards
14 Mohawk Gunship cards
8 Orca cards

and
1883 Credits
3 APC cards

I hope this helps!
