This is for me, I’ve noticed this problem. So Since the update came out, my B-17(not mine) that I edited to have 4 working turrets, I decided to change the tracer color and I did, after that I noticed that all of my guns that had a separate Activation Group was fixed on only one, by this I mean, the rotators work on their specific AG, but the all the guns which shared the same AG as the turret have now just picked a random AG. I did an experiment with turrets and it does the same thing, so more than one turret will do this problem making the builds not work properly defense wise.
But as I said this is happening to me, if anyone else wants to try it, go ahead and if you want tell me if it does happen so hopefully this gets attention and can get fixed.
