Huge bug if you ask me.

When I bartered rat meat with other players, the other player would get that rat meat, and I would get that meat back for some reason, thus duplicating the meat. No idea why though.

For some reason, when the other players with the duplicated meat try to turn it in, they don't get credit for that meat. They get maybe 10GP 10XP or 5GP 5XP instead of the correct amount.

Can somebody confirm that this is still an issue, and provide more specifics on precisely what happens?

I think that this was related to the Pickpocket script issues. Is this still happening?

It is. I was trading it with Fish's PC, I had the quest in my journal while he did not. However, two times it worked well, we traded a single piece twice and it went correctly. Other than that, always duplicated.

If you're thinking it duplicated between me and you, it didnt. I got "lost item: ratmeat" down to 1 unit from the trade and you gained it back.

This should be fixed.
