It seems that the tweet does not relate to a maintenance report feedback for a public flat house in Singapore. The term "causeway" is likely referring to a road or bridge, and the location "0 singapore" does not provide any specific information about the issue being reported. Therefore, it is not possible to determine the type of issue or provide an explanation.
