Finally !

By the time I had 3 items dropped from camps, and 3 items picked manually from the circle,
Other guy had 5 finished items + 4 items on the bench


So he could legit have 7 items, while I had 3.
God bless coin drops


"We will fix itemdrop in next patch" - Riot in June

In rare instances it's now possible to drop a full completed item instead of the two components separately.
