yes I did. But it was not that. I discovered what it was after hours of frustration and meditation.The sound is NOT enough to undergo those familiar steps, it has to be a MONO sound to work. After I converted to MONO in an sound editor  it worked. So maybe it would be a good idea to add/implement this info in that website knowledge base when you build a gun so no one will ever feel the frustration I felt.

I solved the issue. There were planes missing. I forgot about them cause I tried to modernize them and moved them in a separate folder. My fault, apologies.
