Any Dupe Glitches?

Is there any new Dupe Glitches in DayZ? i know that there is one where if you drop something to the floor just before the Server restarts, after the restart there will be another one of the same, i accidentally done this with a barrel, i dropped it and server restarted, after server restart we had 2, but we can do this unless i pay for 40 slot Public Hive DayZ server which is too expensive;/

There is a crash server at will method. But a full body dupe is possible if your fast enough. If you don't own a server it's kinda rude and can fuck other peoples gaming experience up . We have our server run duping for 2 hours a day for the crew and the rest for pvp/exploring.
