It seems that the Twitter post you provided does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The term "throwback" suggests that the post is not recent, and the mention of "tyc sea singapore" does not provide any context or information related to a specific facility or infrastructure that would indicate a maintenance issue. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
