Hi. Sorry for the trouble (and the late reply, as I’m out of town at the moment). I was merging segments of the road in that edit and it accidentally caused the relation to be deleted. I have just split the relevant segment of the road and re-added the relation again, with a slight difference which you can see here: https://www.openstreetmap.org/relation/4270441. I was kind of tired that night when I made the edit and I sort of overlooked a number of changes, so once again I apologise. Personally I merge road segments a lot because it is very difficult with the current software to select the entire route (as in literal routes, like the entire North-South Expressway) when I have to make large edits, which also kind of means some data might be mixed up, and while most of the time data remains the same after merges, I do try to fix them if they conflict or don’t match.

By the way, I do understand Malay, but I feel more comfortable speaking in English because I’m more fluent in it.
