Rare Stance Mod Disappears At The End Of Defense On Mars

[time2getweird]

I recently stumbled upon a Malicious Raptor Rare Stance Mod while completing an alert on Mars only to find that when I wanted to sell it I couldn't find it in the stances tab.  I'm assuming this is a bug with the end mission results screen, I trust that it will be fixed soon, I appreciate any consideration this thread might receive, and I thank you in advance.
