Anyone d/cing? ...A lot?

Not to spread rumors or anything, but some servers seem to be unstable for some reason, and it seems some people are able to duplicate items by selling them in a shop (they buy on another account or a friend buys) and they buyer logs off, the seller DCs, and then theres a small roll back and both people have the items. At least thats what ive HEARD. And its only affecting certain worlds.

Happening all over in Windia. It's pretty much duping without any real effort on their part. However, from what I understand, the whole channel has to crash before this happens. Not just a DC. All of the supposed "legit" people are doing. Ironically it's the same people who talked pomegranate on one person from benefitting from dupes and are now essentially doing it themselves. Hypocrites.
