Hemp vanishes from inventory

So I wanted to craft a couple of bergen backpacks, one of the required items is 5 x HEMP each HEMP requires 5 x weed so to make sure i had enough i harvested 60 marijuana leaf, processed it into 60 weed and then crafted 12 x HEMP that i put into my personal inventory. logged off ...came back later and went to retrieve my crafted HEMP and guess what ...gone

Guys when you spend all this time gathering up gear to use and it vanishes on you for no good reason then one tends to get a bit pissed off. now i know that leaf and weed are illegal items but once crafted into HEMP then this should be legal....it is no longer a drug. It seems that just about every legal activity that I try is plagued by some bug or another.

I can understand why people are reluctant to report any "game exploit or mechanic that can be abused for personal gain" when so much of the mechanics results in personal loss. I would be happy to find one that would make up for what I have already lost and my guess is that is how many people would feel.
