[0.4.13] Crater Map not selectable

Issue description

When selecting a map to start the game with, the crater map is not among the maps that can be selected.

Expected behavior

As an owner of the supporters pack on steam, I would have expected to see and be able to select the crater map.

Reproduction steps

1. Start a new game with the 0.4.13 experimental build.
2. Start a new game.
3. Observe that the crater map is not among those to be selected.

Game version

v0.4.13

We are not aware of the map missing for supporters. We recommend checking file integrity and antivirus software. Did this eventually get resolved?
