Every time i use the chest droppers dispensers and when i put items
in it its like lagging and also sometimes i tried to put a chicken in the
dispenser i long pressed the 64 stacked chicken and its SHAKING
then after it would take 30 mins to put 4 stacks(64) of any blocks or items
and also it lags a split second if you clicked the furnace just like the torches in 0.9.0 this same with enchanting table,chest droppers,etc..
