Comment (by karsten):

 Nope, syncing microdescriptors never worked. The underlying issue is that
 they lack a publication timestamp, which makes it really hard to sort them
 into monthly folders. The way we do this in the "Remote" mode is that we
 parse microdescriptor consensuses and remember microdescriptor digests and
 microdescriptor consensus valid-after times. (A side effect is that
 microdescriptors may be included in two subsequent monthly folders.)
 However, this seemed rather complex to replicate for the "Sync" mode which
 is why we didn't implement that. It would be nice to fix this somehow,
 though it seemed like a lower-priority thing to do at the time.
