When updating a few routes in Ohio, I discovered a broken concurrency on routes OH37 and OH103 in Mount Blanchard (south of Findlay).
I appears there is a shaping point on OH103 that is not included on OH37 between the waypoints at either end of town (NorSt/NorSt_MtB and OH103_S/OH37_E).
Looks like the shaping point should be added to OH37.
