Insurgency keeps changing my settings to default

I don't know exactly when it happens but most of the time, if I think the game looks kinda wired and I take a look at the settings, they are all changed from what I chose. Like motion blur keeps turning on, ragdoll count and filtering get reduced, frame limiter gets turned off, my sensitivity is reset. It is really annoying. Is there any easy way to prevent this? I can't play like this. I have to set up the game every time I wanna play a couple of rounds.

Same here! Been happening to me since alpha.

Motion blur gets set to On (was off)
Page pool memory sets itself to HIGH (was LOW)

No idea what causes it.
