Just for the record, there is no current evidence at all to support any theory of active dupe exploits.

In the past we did experience an extremely brief time where a dupe exploit was found. That method has been patched and is no longer possible.

If anyone suspects actual exploit duping is happening, please report it via official channels.

In an attempt to combat misinformation, in 1.1 we will be adding a way to see if an item was officially "duped" via an intended mechanic.
