Join a server and add it to favourates and join it, when it says "ready" disconnect with Esc and rejoin and do this a few more times. Once you have done this and join the server properly there should be a duplicate character where you logged off with all the same items. EG
DayZ FR (public) *Numbers* Join this a few times and esc when you see "Ready!"
Join the server fully after about 5-6 tries and you should be greeted with a duplicate of your character.
