I'm 99% sure I bought it when Tess was selling it but it's not in my collection. I've had everything else from season 2 for a few weeks now and and since then I've earned over 60 bright engrams but no luck/all duplicates. Is it possible it's bugged somehow? Because that seems like incredibly bad RNG. Thanks for reading.
It's not in the loot pool, but Eververse is selling it as of this reset. Just grabbed it!

I bet you 1% you didn't buy it.
