I was messing around with the dripleaf and i dropped a piece of redstone dust on to the dripleaf and the item disappeared and then reappared 2 seconds later and slowly over 10 seconds dropped on to the dripleaf. Atm bedrock is unplayable for me but entity lag is the only problem other than a bit of block lag.

EDIT: If anyone sees this you can say resolved I figured out that I forgot to turn the randomtickspeed down
