I didn't get any exotics in year 1 but I really wanted thorn. One day xur sold a legacy primary and I thought I'd pick it up but the game started lagging really bad and kept giving me the contacting bungie services message and when I clicked to decrypt it Nothing would happen so I kept clicking until I heard the exotic sound but didn't get anything. I checked the post master and nothing. I was pissed but got over it because it would probably been a year one something anyway so I went to orbit. The moment the screen went black I heard the exotic sound again and was like wtf so I check my inventory again low and behold not one but 2 thorns were in my inventory.
