Well I have little chance for success, but I'm going to go off on my own and work on testing different things to get this theory/method working.
My one question is, what is this lagging process you speak of? You mentioned once about an error regarding trading more gold than you have? Is that it? I imagine with a little effort on my part all the other packets can be sniffed out. OK I suppose I have another question:
After the lagging process, you ask for trade again with the person, do they automatically accept since they think that a trade window is still open or do we have to make them accept that as well?
Thanks for any//all help.
BTW those of you looking for a packet sender//sniffer, just use d2hackit and snifferxp -- easily found and still working...although it is an almost guaranteed ban once Blizzard brings forth the bannings again. But...eh.
