Fallout 4 How to duplicate stacks / anything (After patch)
How to duplicate Stacks / Anything in Fallout 4
The ammo stack duplication exploit works very similar to the original dogmeat method and requires only a few more steps.
To start off, pick a stack of ammo that you have and duplicate it as usual with the help of dogmeat. After dogmeat duplicates the stack for you, it will only show 1 piece of it on the floor. Throw your original stack next to it on the floor and it will change the amount to the original stack amount.
DON’T PICK IT UP YET and instead quicksave the game, back out into the title screen and press continue to reload the latest quicksave. Back in the game, you are finally able to pick the 2 stacks up and get the full amount.
You can do this with all stacks and if you want to make it a bit more efficient, you can duplicate a whole bunch of stacks for different things and then save, back out and reload instead of loading the game after each duplication.
