hmmm i dont have any screenshoots or anything but i went to a pirate station and found some recipes and picked em up, server was lagging then so i had recipis both in inventory and chest, i destroyed the chest and the recipes where dropped on the floor, then i dced from the server and when i went on some time later the recipes was in my inv and the floor. i dont know if this works with other items aswell but it could be a pretty hard server destroyer since noone will be able to tell if one dupes or not when dcing in lagspikes.
