Cartographer Maps Go By Seed

I had an old world which I partially explored before the update. When I bought a woodland cartographer map, its picture led me to the middle of a swamp. This is likely due to the fact that TU31 changed all biome generation. I think an easy way to fix this issue would be to only check ungenerated chunks with the map.

*To recreate: *

Have a world explored before TU54. Buy a map from a cartographer. (either will do) Go where it tells you to go, and it can sometimes lead you to already generated chunks with no structure to be seen.
