This is 3 separate tracks, there's nothing wrong with Syfydryn to Nant y Moch. Syfydryn to Llety-Ifan-Hen is also fine, although getting a tiny bit washed out at one point. It's Bwlch yr Adwy that is where the problem is, I thought the repairs had started? So as you look at the map, as far as I know the southern and eastern sections are fine.
