While questing on my Timerunning character (Specifically the character I’m posting with) in the Dread Wastes I completely filled in the map and earned the achievement “Exploration->Pandaria->Explore Dread Wastes” on May 21. However, what I didn’t notice at the time is that I was not given credit for the identical achievement “Remix: Pandaria->Exploration->Explore Dread Wastes”. Specifically, I was not given credit for Kypari Vor region.
I’ve gone back to the area several times on a Dragon Riding mount, a flying mount, on a ground mount, and on foot. I’ve gone to coordinates suggested on WoWhead, and followed youtube videos. Nothing I do gives me credit for Kypari Vor. I’m guessing the game gave me the credit for exploring it for the OG achievement, and now that it has won’t check again for the Remix version.
