[V0.28 XCE ground combat] Farmers gun not visible (minor)

[thixotrop]

As title says:

When a soldier picks up the shotgun "from the dead cold hands" of a farmer or his remaining goo, the weapon is not visible in hand or weapon slot only in the equipment screen.

The soldier can shoot with it, although that I have the feeling the weapon behaves different to the Xeno-carbine.
