Brimstone mount barding appears to have been removed?

The barding that matches brimstone mount is no longer in the mount wardrobe. I use it every season, and now it’s suddenly not there. Can anyone confirm please?

This barding was first available in the season Duriel was first introduced (season 2?). I think it’s called Brimstone Harness, but can’t remember.

It’s disappointing I spent hours grinding for this, only for them to remove it 😕
