1.10 Chunk Generation Failure

I started a new Creative world in the new 1.10 update (which doesn't seem to be listed on the Mojang site). After a bit of exploring, I came across a strip of Desert/DesertHills/River biome within an Extreme Hills/Extreme Hills + biome. A malformed village is inside the out-of-place chunks. This might be an issue with village generation.
