Female citizen can build military buildings

[Karamel]

Although you can't order a female citizen to directly build military buildings (barracks, walls, towers…), you can order the construction from a citizen soldier then send exclusively female citizens to build it.

AFAIK, it was intended this way. It means you need at least one male to build military stuff.

If it wasn't intended this way, it would be easy to fix too.

Well, it's a Spartan bonus to have females create military buildings.

It's very unlikely not to have any male on the map. You don't need him there to build it effectively, just order the building even from far accross the map and into the battle. Once the fundations are set send the females waiting at home. That is, the Spartan bonus is just a convenience to avoid a few clicks.

Seems like an exploit for me.
