An error with the upcoming PROJECT map's naming.

The map is using the incorrect terminology.

Substructure: An underlying or supporting structure.

What you were actually looking for is:

[Superstructure: A structure built on top of something else.

• The part of a building above its foundations.](https://en.oxforddictionaries.com/definition/superstructure)

I don't expect this error will be corrected as promotional material for the map has already been released, but thought I'd point it out regardless so that such errors might be avoided in the future.
