Had a bug where I can't shoot when looking at a tank, then could fire when not

Good Afternoon,

I’ve recently had a bug, I have no idea how or why, but attempting to fire, whilst looking at a tank did not work.

I attempted to fire whilst looking at the tank, checked the binding (which was set to left click still, rebound to left click), reattempted to fire, did not work, then aimed off at the ground, away from the target, and then my main gun fired.

Using the Magach 6M, this has happened once or twice before, which I initially put down to connection.
but this spanned a long duration of time, approximately 30 ping, no packet loss.

edit also had no damage, had not been engaged at all by this point.

what in the world caused this??
