There has long been a bug where if I were to point at an enemy tank in sniper mode, the reticle would immediately do a 180, and i'd all of a sudden be looking behind/above me, with my turret and gun swinging around to what i was now aiming at (always nothing).
Since 2.5 has started, I have noticed an alarming increase in this happening. I don't have to be in sniper mode for it to happen anymore. In 3rd person mode, the reticle will turn 90 degrees (usually to the left) and my tank/turret (played mostly TDs since release) would turn 90 degrees at what i was now aiming at, even though it was never my intent. You can imagine how many times I was shot in the side of the hull/turret because I look at an enemy and my tank immediately and involuntarily shifts my aim, thus turning my hull/turret
