It could literally be dust on your mousepad or table where your mouse is. Same with a random hair in your mouse optical thing. That’s happened to me for bullet and I don’t always notice
Dropping pieces on the wrong square in Bullet
If you need help, please contact our Help and Support team.
Seems like all of the sudden I'm dropping pieces on squares I don't intend. Like if I move, but change my mind and want a different move, its still landing on the 1st square even though I haven't let go of the mouse. This is bullet and I'm sure I'm at fault some of the time but not every time....
Anyone else?
