Duping Help

I duped successfully before release of 123.4.4
Ever since the update, duping has been a failure.
I use the standalone clients for correct duping, work with the hanging between vault and nexus...etc.

Could somebody give me a detailed tutorial on duping.
Correctly and efficiently.
Thank you kindly.

I know how you feel, I've been duping and then, not to long ago, it just stopped working and I haven't been able to get it since. Alas, I doubt anyone can help anymore than they already have. They are several guides on it already; the most they could do is just dupe for us, but I doubt anyone would be that generous with their time. xD

I have just gotten two successful dupes in EUWest (no other servers seem to be working with it) by doing alt+f4 right as it says "Connected!" and not just "Connecting to...", so this might be the case. Try heading to EUWest and doing some duping.

Why does everyone want someone else to do work for them here -_-

Yes I've noticed the atrocious grammar too. =P
