A first-person stone throw occurs earlier than the player’s display. The bug happens steadily, it is enough just to sharply move the mouse at the end of the casting ability.
I also want to note that at the moment of the first person throw, the stone disappears for a moment.
At the same time, when watching Replay, the animation is displayed correctly.
Most likely, the problem appeared (or got worse) after this change.
Accretion: Cast time reduced from 0.75 to 0.65 seconds.
