The pale oaks planted by players do not contain the creaking heart

To see the bug,you should set the experiment "winter drop" on first.Create a world and enter in.Then you can look for a place such as plains to plant the pale oak saplings.Plant them 2x2 and use the bone meal to speed up their growing.When they grow up to a pale oak tree,check them.Break all the logs,you will not see the creaking heart.
