How to dupe
No I'm not going to give the specifics, but it looks like one way to dupe (guessing there are more) deals with chunk resets (when everything stops working and logs you out to the login screen),
I was doing something, mailed some wood, did something, something happened, I had the wood in my inventory and the person that I sent it to had it in their mail. If it is reproduce able, it would explane why a single chunk crashes 20 times in an hour.
I'll see if I can't get into contact with a GM to see if we can't reproduce the dupe. Might of just been a one time thing, I didn't want to mess with it for fear of banning.
