Today I took a third run at the level 35 Prison of Elders with my 34 titan and two good friends and their 34's after spending a good 3 hours on it last week, another 3 yesterday, and about 4 today. After being forced to ascend both a void sniper and machine gun on each of us, we prevailed by the skin of our teeth. However, even though I was never told this by the game in any way, because my bounties were full I was unable to receive an elder cipher, required for obtaining one of the sweet new exotic weapons. I now have Variks glitched out in the Reef and first of all, I can't even get the main reward for completing this challenge, and second, I now have a permanent notification for the Reef that I cannot get rid of, and this is to be honest the most infuriating part, because not only do I now not get an exotic, I also expect to sometimes forget that I don't actually have something to do in the Reef and go there anyway, only to be disappointed once again. I think this, if anything, should at least be patched, because this is clearly poor game design. Ugh. Sorry. Just ranting.
