Summary: Our caching mechanism was storing unfinalized block heads and once they were finalized returning the older value which is incorrect, so in this PR we are ensuring that if the cached block is not finalized to re-query the block. NOTE: there is room for optimization but for now this is a solution to get rid of the bug.
