Ok so, when you are in a party and somebody starts a story or side quest boss fight you are teleported to the fight and forced to help. Whether you’ve fought this boss or not you get about 10% of the exp as you get the first time fighting it. This is fine.
However, if you fight a boss for a quest you’ve already finished you get zero drops. No silver, no items, no anything. If you have not taken this quest yet you get full item rewards, and will continue to get full item rewards until you finish that quest yourself.
I believe that anyone who has finished the quest should still be entitled to any drops from the boss. Especially since sometimes people do quests slightly unaligned so that you might finish a boss quest and then your friend was behind and helping. Then they caught up, so you go to help him and you get no drops even though they got full drops twice.
It could be a bug, it could be a design choice. I’m not really sure which, but I believe helpers should get full item and silver rewards every time. Not just every time until they finish the quest themselves.
