Do you think maybe this has something to do with it? Its just a timing 
issue (both in my case and when you see it before M4) and in some cases 
the keys aren't fully installed and the request either gets dropped or 
just isn't encrypted correctly?

Like I said originally, its not like this issue is severe, we can just 
request a neighbor report later and that does work. It was just an 
observation and didn't seem right.
