Once upon a merry time ago I was the first kid on my block to beat Diablo 2 with a Paladin. One thing that I hated was farming for runes and gems.
We discovered pretty quickly how to use multiplayer mode and a back up of the player file to dupe gems and runes so we could create things like our triple socketed perfect diamond great shield in a lot less than the forever that farming offered.
Has this bug been patched over in the latest patches? (I will follow up with a question about the best way to farm runes/gems that I can use on battle.net)
