Living weapon destroyed

So i had a unit equip the living weapon, one of the things i paid extra for… And the gun was destroyed with one grenade from an archon and thats it? No more gun for the whole playthrough
Should have a way of getting it back, unless im missing something

Don`t worry, those weapons are useless anyway.

They deal very little damage.
The only up is, that the don`t need any ammo.

I dont have living weapons. But if you cant produce them then Destroyed is destroyed i would say
