If you have a good example of this happening, send us the film and we can see exactly what's going on. Most of the time it's just the strike angle being greater than what the shooter thought it was but we've found plenty of issues in various vehicles by reviewing films. I don't know of anything that would have changed in the latest version to affect this aside from what has already been listed in the readme.
What kind of issues are you finding if you can say so? I would like Hooter to send you a few of his films, he's logging hundreds of ricochets and I am starting to experience them as well - my issues have come from shooting a tank in the rear, for example and Engine shot or Turret, and the rounds will bounce 8 of 10 times, Knowing the armor of an M4(76) rear, vs a T34/85 at 600 yards - I logged over 20 ricochets.
Even shooting a Panzer from the side at 600 yards, I thought I might of aimed towards the front of the turret, but on the film it shows dead center on the side, only to watch a HVAP bounce off.
I might of had an issue however due to a virus which was attacking my frame rates. I got fed up of my FPS dropping from 90 to 27 everytime I moved, I ran a virus scan and it seems things are back to normal game wise.
