I have an AgentEx ally. He has been walking around with an Ares Gamma Mk4 in his primary weapon slot and a M21 Assault Rifle in his secondary weapon slot. The M21 is a Ammo:24 Auto weapon.
But I have just completed the Yakuza ladder. So my AgentEx ally stuffed the M21 into his backpack so he could use the MT Mongoose Proto instead. This is an Ammo 12 Pistol weapon.
When he next got into a fight he was weilding an MT Mongoose (good) with 20-some bullets (impossible). This is left over from the last fight when he used his MT21. I forgot to check if it was pistol or auto ammo that was expended as he shot things.
I don't know whether the fact that the last fight in which he used the M21 ended with the M21 not being fully loaded was significant.
