I dont know how you lost items since the new build i have duped over 10 ammys and lots of pots. Anyway i started after the build duping, and i find it luck to dupe successfully.

i dupe like 80% on my mule but 10% on my original acc

Patience, young grasshopper.

I give up on duping... I lost my bulwark and several other epics using the method shown on the dupe threads... so if anyone can dupe me ammys that would be great... USEast 3 KalFoxis

My net so fast, cant dupe. :C

xd

i'll give a try again.... thans god i got some pots from gods today >

One last question, is fast or slow Internet better for duping?

I have been having the same problem. Around when you about to drag the last item make sure it says Connected! then drag last item to inventory slot hover over inventory slot until it says Connected! again drop item into inventory slot either nexus or close client.

You dont need to do that.
You can drag all items into the vault.
You can go sleep for 8 hours. (if it wouldnt disconnect of course)
You can come back and when timed right you can still dupe.

The duping was made somewhat harder yes but not really.

I suggest trying for around 5 times.
If you get it, great.

Otherwise just do something else and try again later.
I usually get on 1,2,3 try.

If you read correctly I said the last item (meaning it's the last item in your vault you're deciding to dupe).
You can use other methods but this has been the easiest method I get first try since the update.
I still can dupe and the made it harder in the 123.5.1 update.
