Hello, me and a friend noticed that when we do the Undercity in party and put a tribute none of us gets the loot (guaranteed runes for example) we tested it several times.
Then we dropped party and each of us did several runs solo - and everytime we got the guaranteed/tribute bound loot in the end. All runs where done on Torment 3 or Torment 2.
All runs also where 4/4 reward upgrade runs.
Please fix - or state its solo content and no group content.
