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.
