As of the patch today, Glitchy's method didn't work for me. This is sort of like glitchy's method:
You only need 2 of the item you need to gather
Put them into 2 stacks of 1
Drop 1 in the back, then back into your stack
This should count as gathering
I've gotten this to work for 2 items (all i had to test) let me know how it goes for all of you.
