Items randomly disappearing from inventory or boxes

ok, i have had the same issue.. the first time i put 1700 scrap in a box.. and it vanished. i looked in every single box in my base at least 5 times each, and nothing. i though perhaps i dropped it on Accident... until just now.. i crafter 2k GP, put it in a box by my TC and 30 seconds later it vanished. 

is this a glitch? or a new hack  for hackers

I don't know if its a FacePunch bug or glitch of some kind. I drove myself crazy looking everywhere in case they were dropped (I used a salvaged hammer to pick up crafting workbench to 'look underneath', just in case. But nothing 
I had  5 empty slots in my inventory (3 in inventory and 2 on my toolbelt), so I didn't have a full inventory.
Its pretty confusing when stuff just disappears like that, literally a second after crafting it.
To be honest I kinda thought for a second that maybe my inventory was getting accessed somehow by a hacker LOL - but that's a little too paranoid, even for me!
