I am grinding for a destab/repulsar riposte. My inventory was full when I spent engrams but the weapon at my postmaster is an engram I cannot attain. This has never happened before but please make it destab/repulsar when I am able to pick up, I have been grinding this roll since day 1. Unsure why this happened. This is new for me. Cheers to Marathon as well! Thank you for your help in the matter. Hopefully this is an isolated event.
