Key bindings messed up

[Smaguris]

So far I had normal key bindings, but today I start up the game and all of a sudden numpad keys don't control camera movements anymore and instead switches between cameras, i button doesn't reset my car and just does nothing and so on.

In controlls settings it's showing correct bindings but the keys aren't doing what they're supposed to do..

If you disable NUMLOCK, the numpad will act as arrow keys (hence will drive the vehicle instead of controlling the camera)

For the other keys, that's something else more likely.
Try to simply reset your bindings (RESET ALL button in the Controls menu) for those.

Numlock was enabled. Also it seems like it fixed on itself the next day without me doing anything. Odd
