Since a recent patch or hotfix, I have noticed that players firing at me are not showing up on my radar. Sometimes they do, if I'm close, so I figured this was a nerf. But the same is for vehicles. I have had vehicles fire at me and could not find them. I didn't think the Vehicle Stealth Defense Cert prevented detection while firing, but I just got shot down by a scythe and couldn't see it until my kill screen popped up. Did this get changed or is it a result of performance (e.g. lag) or exploits?
