Nitride Katar Missing From Shop

Good morning, 
Just a heads up that it looks like the Nitride Katar variant is missing from shop for purchase. 
Can we have back or is it removed permanently? I'd like to put together my Katar idea after finally saving up enough exotic shards :(

Scrolled through a couple time to try and find it. Cheers team! 
No worries if there is known issues with the item. Thanks again for the work you guys do, love the game
