There's a bad bias somewhere. Even when our GPX points are clearly, totally on a link, a different link is used.

Ah. This was due to prepare.min_one_way_network_size=200, and hidden, because this is by default 0 in GraphHopper, set to 200 in MapMatchingMain, and set to 0 again in the shell script (now gone).

The correct road was just being removed.
