You're correct. I went back and totaled the MC I'd won and it does show up.
Thanks!
I can only speak to my experiences so far, but I believe the reason I got the UNKNOWN ERROR, was that I received a prize of "1x Improved UAV," even though I've never unlocked the Improved UAV Upgrade, meaning it couldn't be placed into my inventory, and the game had a hiccup, thus dumping all of the prizes I would've received in that "redemption batch" into the trash.
