dupe exploit for v1.3.

It seems like i can't find any topics regarding the dupe exploit. I was wondering if the mush shop and server check dupe exploit still works with v1.3. If not are there still other methods of utilizing the dupe exploit?

Or if there is a topic regarding this issue, please post the link, the search button is acting weird.

I thought its v1.4 now. And should be patched. Since there was a little small rollback.

wow theres still a dupe exploit O.O
