I noticed this as I was acquiring bounties from thebios app.
I would delete a quest or a bounty and then acquire a repeatable bounty- except it wouldnt give me a new bounty in game.
But i would still be at 63/63
I am looking at my page- 23 bounties and 10 quests.
I do not have 63 items! There must be phantom items from times when I tried to pull a new one but they dis not get delivered
