Two annoying things about Far Cry 6. My right stick keeps drifting upwards. You're probably thinking "that's your controller, not the game" but it only happens in Far Cry 6. I've tried cleaning the controller anyway, but no change.
The other thing is 100% Far Cry 6 related. It forgets key bindings. I only change two (the button it uses for "interact" and to holster my gun), and every so often when I start to play again I find that they've reverted. It's a trivial annoyance, but an annoyance nonetheless.
