Ok, I thought I was just imagining it before, however I am now sure that upon receiving a Farsight Telescope, it did not accumulate in my inventory.
I am pretty sure this is the third time.
I know for a fact I have had 3 in inventory for a bit now, and have been waiting on 3 more. I was really happy to see it in my loot, and quite disappointed it was not added to my inventory.
This is frustrating
