So I was trying to complete Grasp of Avarice with my friend this week to finally get a hold of some of that sweet looking armor for transmog. Well, everything was going swimmingly until the final encounter. We get there, and first issue, the Vandal and the Shank don't spawn. Weird but alright, carry on. Then we notice that the boss actually isn't moving, let alone attacking, just looking at us and thinking very very angry thoughts. Again, weird but we continue. We get the Scorch canons and go to open one of the Pods to get the Engrams to fall out...only to see that the Engrams spawn, yeah, since we saw their animation behind the thing, but it never opened. We tried it on the other two Pods and we managed to force [b][i][u]one[/u][/i][/b] to spawn and drop onto the floor. We relaunched snd restarted without success at least four times. Even switched host. Now with just the two of us doing and work approaching soon, I said screw it and we'll try again later. Then I join his Xbox party yesterday, hear him and his fireteam on their Flawless run get to the final encounter and they tough through the Engram shenanigans enough to start damage phase....only for the boss to be immune. However, Damage phase itself lasted until they left the dungeon which means that damage phase on the unmoving boss doesn't matter and lasts forever. I'm not sure what can be done or how this could happen but I would really appreciate this bug to be fixed sometime this season.
