Today, I spent 750 gems to participate in a Traditional Historic Event. The event description clearly stated that it would provide packs from non-Standard sets. I achieved 3 wins, which should have entitled me to two packs from non-Standard sets. However, I received a pack of Khans of Tarkir cards and a pack of Kamigawa Neon Dynasty, although one of these is a standard set.
I believe there was a bug in the event, as I received incorrect and unneeded rewards. I reported a similar issue several days ago, but it appears this easily fixable issue persists. Therefore, I am requesting compensation for the entry fee.
