Argh! Well, I’ve gone and broken that Route ‘338e’ again, sorry -
because I added a further route (338f) which has even more loops and spurs, and I had to split one of the existing ways to do it,
so now BOTH those two relations have their ways all in the wrong order again 
Route 338f is Relation: 338f (18822054) | OpenStreetMap
and Route 338e is Relation: 338e (18802944) | OpenStreetMap
I can only plead for volunteers once more to repair these on JOSM.
(The bus stops themselves are all present in the correct order.
For ease of reference you can also see them here:
338f - Newry City Service - Bessbrook, Charlemont Square – Ulsterbus Town Services – Bus Times)
