Villages float near blended chunks and generate wrong village variant

World originally generated in 1.6.4.

 

When blending chunks from this old world, the village that spawned in at this location is floating and not the right type. The village that generates is a taiga village but a plains village should generate instead. Maybe chunk blending should just prevent villages from spawning near the borders of old/new areas?
