UR, Uranus Disruption Didnt get stated Relic reward drop

[RiverOfgorillas]

I was playing Solo on Ur, Uranus Disruption.  My goal was to get Meso N9 relics.  I got one as a reward from both the 2nd and 3rd rounds.  I extracted and to my dismay, saw the end mission screen stating that I got a Meso L1 and Meso R2 instead of the 2 Meso N9 that were show as dropping while I was in mission.  This is really frustrating!  I checked my inventory and did not get any Meso N9 relics from this round.  Why should I spend my time grinding when the game is gonna tell me I got what I want but then fake me out like this?
