I have a problem in The Stan misson,I can finish the rifle range and the gauntlet but everytime when I walk into the pistal range to begin qualifiy,my pistal mags all disappeared and I can't reload . If I take M9,when I walk into the pistal range ,it become Glock17 and one m9 mag left,if I take Glock17 ,the G17 mags still become one m9 mag left.I have all the required addons and I'm running ACE2
