Unique items not dropping on any difficulty unless I salvage unique artifacts

I have been playing minecraft dungeons 2 since launch and I've came across this bug over the past few days where on my online profile I cant get any unique item drops no matter the difficulty unless I salvage some unique items prior to fighting a boss or enemy. I don't have a full inventory! I have redownloaded the game and it was fixed for literally like 1 session and I only got 3 unique drops that whole 2 hour boss killing session I've tried all the bosses including the mossy golem thing and it never changes still no unique drops. MOJANG Please Fix Your Game!!!
