Sapper rare restriction not detected

Hi!

There is a bug with the sapper, in skirmish I can use two units of sappers whenre they are rare, there is no exception.

Thx!

Two Units? Or two Squads?

A base = a Unit. There are two bases in the Squad.

So, two Squads? Yes, that's not legal...

Looks like I was missing the building limitation to make them rare.

Fixed, will go out in the next update (hopefully this week).
