Degrading data quality in Manakara and Vohipeno districts

Hello @Allyas: Came here to flag some issues regarding the road network on Manakara and Vohipeno districts. As you know, our mapping team at Operation Fistula made a lot of effort to maintain the quality of OSM in those areas. But these issues created by your team are causing problems when using the road network data:

  • Floating islands of roads. They were clean when we left, but now there are many islands of roads

  • Paths crossing very large and deep rivers. We had those data validated by our field team and with hundreds of geotagged photos from the field, and I know what I mean when I say that your team has added a lot of ford=yes crossings where it is always impossible at any time of the year. For example, the Matitanana river around Vohipeno (way 393121947) is more than 200 metres wide and even crossing it by boat is rather dangerous.
