Ever since the new version was released my kill-log would sometimes not display the latest kill on the log until another kill has occured. I find it quite frustrating in wars when you need to know who wins what gun battles. I think it has something to do with the resolution. I play in 1920x1080 because I also noticed the same thing in 1.5.0 when I manually changed my res (which wasn't available in settings) by going into the config and the same thing would occur.
