One week ago, in changeset 152999693, I remapped Registon ko’chasi in Samarqand completely between Universitet bulvari and Islom Karimov bo'gi: originally this road was incorrectly mapped as a dual carriageway, but there is in fact no physical separation between the directions. It is a single way with lanes=4, lanes:forward=2, lanes:backward=2. This can easily be verified by a personal survey of the street.

It looks like my correct tagging has now been undone. Please tell me whether you did this in this changeset, or if the fault lies in subsequent changesets by use ChromeLotus.
