PS4. Playing coop online. Unable to claim Haedrigs on Monk while in party with Necro. Went to single player and was able to claim. But Haedrigs gave 2 helms and 2 gloves in error. Now my progress is slowed.
If you collect Challenge Rifts, you can use the mats to convert the duplicate set items which will actually speed up your progression since you can get a 6-piece, if lucky, without needing to get the other Haedrig Gifts.
