Problems with volumetric lights using lamps was not sun

I had the Armory open and doing some tests, among these tests was to do lighting tests. I used the volumetric light using a sun lamp, while the camera was in a box with holes, so far so good, working and beautiful. However when adding another non-sun style lamp (such as spot), the armory did not build and play, the problem only happened if the volumetric light option was enabled, if I changed the ownership of the spot lamp to sun , it worked. I tested with all the different lamp options and the result was the same. Do I have to activate something I don’t know or is it a bug?

One of the things I wanted to see happen is a flashlight light effect with the volumetric light on a spot lamp.

Is it possible to provide a test file? It may be useful to solve the problem.

Of course! forgot to put in the post.
I created another file and get it to play with another lamp, but when I put more than one lamp in the scene the game didn’t play.
