Really? Odd.. out of all my years of playing, I haven't found a dupe.. unless you were talking maybe about the auctioneer bug or something?
I don't know about OSI but Freeshards I know it doesn't exist.
There was 1 dupe on RunUO servers. It was through vendors.
There was then anotehr vendor exploit which was sort of duping gold (the vendor basically pumped gold into the server)
Then there was the house customization bug which dropped gold into your bank.
