Hello. I'm posing this because I couldn't personally find any information about the bug I experienced. I recently attempted doing a Nightfall strike with some of my friends and we got the Strange Terrain mission. All went well, except for the parts where we got to the relics. At the first area where you have to throw the relics we killed both the Knights and managed to throw one of the relics into the crystal, however the second relic completely disappeared. My friend said he was looking at it and it vanished as he was picking it up. No more knights spawned that would give us relics so we had to restart. Tried it again and got to the area with the Ogre boss and the four crystals. Broke one crystal, but on the second relic the same thing happened, although this time it seemed the orb rolled past the taken barrier that goes to the next area before also vanishing. No more enemies spawned again so we just gave up. Left a bit of a bad impression for our first Nightfall mission. I'm not sure if this bug is that widespread but It would be nice if it was looked into.
