Im not sure if this was some isolated thing or if other guys were having the same problems. I asked and did not see any response. When I upped a set of B17s today and had to hop into my tail gun, only the gum that I was currently using was firing. I switched from 1 position to the next and so on, but only that gun would fire. So, I relogged and it was the same result. Only the position I was gunning from would fire. Please look into this.
