Didnt receive the 2 Mythic cards reward from Rank 12 in the Midnight Hunt mastery pass.
Playing on a HP Pavilion Laptop, did my daily quests and weekly wins to get enough XP to reach rank 12 on the Midnight Hunt mastery pass and did not receive the 2 mythic cards reward from owning the pass. I did however get the reward from the free version of the mastery pass, which was a single pack from MNH.
I reached rank 12 as well and didnt get the alert saying I earned anything. I went to packs and did receive a pack, and then I went and checked to see if I earned any new cards and found the 2 mythics I was supposed to get sitting on the first page in the deck building screen saying "new". I hadnt had a copy of Hostile Hostel before or a second copy of Lier, so im fairly sure I did earn them. Just the normal animation showing what I earned for completing Rank 12 did not appear.
