I've been seeing a duplicate helmet bug. Not sure if it's trainer- or just game-related, but when I headshot a guy and his helmet pops off, he'll still be wearing a helmet afterwards. Sometimes if you just graze guy's head with a bullet his helmet will pop off and not kill him. I've shot 2-3 helmets off the same guy a few times, and he'll just be standing there next to a bunch of helmets on the ground. It doesn't seem to break the game and it's kind of funny.
It looks like a few ppl are having some crash issues in the weapon load out screen, same for me, but i get a directX 11 popup box about it, so i'm thinking it's not trainer related (or it is? ).
But some of the earlier Elites in the series had the same problems too. As you said, not a big deal or game wrecker. As for ppl having multiple weapons after swapping them in game, easy DON'T swap weapons, be happy with your load out prior to doing the mission, and yes it defaults to start weapons in convos before you start missions, eg. talking to Weaver or partisans or the "Mob", a great trainer for this game, so thank you guys.
