blocks sometimes don't break and when they do its laggy

Put the summary of the bug you're having here

I was going to break the blocks of a tree and the block didn't disappear and after I would say 5 ish seconds later it will either stay unbroken or finally break sending the entity to the ground
I feel like it should break right after the block breaking noise is heard

it just randomly happens and I have no clue why or how to trigger it
