Dear Destiny-Team and/or Destiny 2 Community. I've got a small problem here. So during the past 2-3 days, I've been trying to get the Pit of Heresy Solo Achievement. I didn't play 48 to 60 hours straight, so I took breaks in between my attempts. I never reset my dungeon checkpoint though, so I could just continue later on. Now, this is where it gets interesting. Just a couple of minutes ago I finally managed to finish the Dungeon after killing the boss. I got my pinnacle gear (which in this case, was just a 964 Power cloak just like the one I got the week before, which is scripted but also very sad, but that's another topic,) and I was super hyped to get that sweet Usurpator triumph for 200 triumph points. But nothing happened. So, long story short, I get teleported back to Orbit after looking at the Post-dungeon screen in awe and agony for 40 seconds and go to check my triumphs. But indeed, no triumph had been earned. Now I'd wanna ask y'all if anyone had the same problem before or if this is an individual case. Does it have something to do with the Checkpoint? Please help! Thank you for reading in advance.
You need to do it in one sitting, without ever returning to orbit.
