After playing destiny 2.0 for a while I found the abandoned quest tablet and being the completionist I am I wanted to complete them all again to clear it :) I completed fruit of the garden quest first for the strangers rifle, and then all at once so I could minimise my tower trips. However upon completing the hive quest chain (not the crota one) the speaker restarted the Fruit of the garden for me again and I'm going through it again. I don't have anything to level up to see if I'm being rewarded or not so I'll update you guys when I finish it to see if I get another strangers rifle.
