A friend and i were playing on our shared save. My friend was on pc and i was on xbox. during our playthrough we've been instakilled by fall damage but we didnt fall too far to give us that much damage. but when we landed we would ragdoll ontop of our buggys which would give us another instance of fall damage and insta kill us even though we would have near full health. we can provide proof of this bug it wasnt hard to replicate as it happened to my friend around 7 times and only once for me. the other bug is that i cant see my friend's (who's playing willow) icon to know where he is. i cant even see him when he goes down.
