Do you have an updated gamedata file then? Running sm 1.6.2 4559 works pretty well but has the issue of the fn fal and mossburg not reloading, ever.

Edit, a month later, I modified the plugin to have working barricade hammer planks, the mossburg, fn fal, and something else that was broken have unlimited ammo now. It was a simple fix, works well.
