how do you update your 14w08a server to 14w10c without loosing all of the items you have in the chest, inventory and in you encerchest?

i found a solution to to problem. To fix this ona server you just start the server with 14w10c and teh you put the players folder in the map folder and delete the playerdata folder and start the server again. It will create a new playerdata folder with the old players in it with all the items you had.
