Have been noticing a few glitches with 1.5. Perhaps it is packet loss or something of the ilk.
I had one, a M103 was driving up half a tank length behind me, I shot across with a clear reticle but somehow it went into his turret.
The more obvious one, was when I shot at a tank, I clicked to fire, my reload started and a shell came from my ammo stock, however there was no shell sent, no visual or audible of a shell firing other than what I said, and no shell impact anywhere. The tank returned fire on me and killed me. I don't know if it's packet loss or server side lag? I have an overwolf vid of this happening if anyone cares to see it. https://outplayed.tv/media/1XbdZ/wot-death
There have been a couple other odd things like this since the patch.
