I have found that this bug occasionally along with rollback causes some duplication of items. As an example, I built a small structure and also took 6 of 12 lily pads out of a chest and placed them on the water. The game crashed, structure was gone however the lily pads remained in the water and were placed back in the chest. Similar thing happened with a diamond pickaxe. Started with 1 diamond pick axe (efficiency 3 & fortune 3). Made a 2nd. Enchanted it with a silk touch enchanted book. Game crashed and undid the silk touch enchantment. The book was back in the chest it was originally kept in and the silk touch pick axe somehow became a duplicate of my original pickaxe with efficiency 3 & fortune 3. On another occasion I killed a sheep and after the game crashed I was left with a living sheep and the wool I obtained from killing it before the crash.
