Reduced river and road vertex count slightly
Fixed riverside and roadside topologies reaching too far around rivers and roads
Tweaked river and road splat adjustment fade
Fixed rivers sometimes randomly failing to be added to the water map (physics weirdness)
Added normal smoothing factor to road and river meshes
Fixed mesh normal discontinuities when rivers and roads have to be split for collider perf
