This has only happened to me and it seems to be when I'm aiming a weapon and strafing, sideways or diagonally, and it aims the gun down for the realism bit of it as not many cops just aim their gun up in the air and strafe sideways, to which when you bring your weapon down, it happened to me, my character lost all control and started running from the cops and shooting at them, I had temp control for maybe 5-10 seconds at a time and it was only to aim or to try and shoot the cops from arresting me, however in the end they shot me and killed me, to which my game crashed, I don't have my game very heavily modded and it's happened to me twice, even with the new 1.0B
