IsSurfaceFertile not working properly on Nasdara, allows placing gardenplots and digging worms on road surface.
I've tested this on both the release and experimental versions of 1.30. On Nasdara, actions that use IsSurfaceFertile appear to be detecting the surface below the road instead of the road surface and allow placing gardenplots, digging worms, or other actions that shouldn't be allowed on a road.
This only applies to actual roads, moving onto a bridge works properly and doesn't allow the actions. Trying on the runway surface also doesn't allow the actions.
I also tested on Chernarus and the problem only shows up in very small areas near the intersection of two road surfaces. Most of those areas are too small to actually allow placing the gardenplot, but digging worms and similar actions work.
