Missing Boca Juniors Retro Kit

A few weeks ago, I was looking through the retro kits that are part of the season 6 items on ultimate team. 

I saw the Boca Juniors 95 kit. Alongside other retro kits like Real Madrid, Palace, Chelsea etc. 

The expiry date said that they had over 30 days left. 

Cool. I came back the following day, with 75k from rewards ready to buy the Boca Juniors kit. But it had DISAPPEARED!

Checked everyday at 6pm. Both on console and web app. Even had friends check. Nothing. Straight disappeared. Disappointment. 

What happened? And will it ever come back? And if so, when?
