To note: This only applies when in 1st Person View, not 3rd Person (which has never rolled).

Roll camera occurs for me in 1st person, not in 3rd. It shouldn't occur when in 3rd person

I am in 1st person view. Uploaded a video to demonstrate

I need to clarify: When I was running 0.30.113860, I am under the impression that 1st Person Camera would roll if I rolled as prone.

I've now noted that my version is 0.30.113899 and I'm no longer having view rolling in 1st Person Prone.

Just in case the version makes that much of a difference, but I can't exactly pin it down, I was on 113860 for a very short period of time before I had to go to work and when I came back, I had been updated to 113899.

I can confirm.
If you are in first person view, go prone and then try to roll left or right, the first person view is not rotated to reflect the roll, instead it is translated as if the character was crawling sideways (strafing). Third person view however shows correct roll animation. This has been present in ALL versions for me since beginning of early access on Steam.
