Hi JR,

I have been running the measure_roads function on a large road network. After running without issue on over 1000 roads, I got this error:

> corrected_road <- ALSroads::measure_roads(road = road, ctg = ctg, dtm = dtm)
Road 1 of 1  Progress: ...................Error: Internal error. A MULTILINESTRING has been returned. Please report
>

I have included a reproducible example with my data and code.

Let me know if this is something I can fix easily.

Cheers, Lithy

Good, I added this error yesterday to cactch limit cases. I'll have a look

Fixed. I'm confident this fix won't create more trouble. Yet you may encounter other edge cases with weird road geometries.

@jfbourdon update, my previous bug fix is generating this new error.
