If you experience any lag whatsoever in mission please call it immediately. Do not wait until the battle develops further as this can lead to misunderstandings and bad will.
Speaking unoficially for the Kitties, should any of our players claim a lag issue AFTER a kill is scored on them, the points are fair game to be counted by our worthy adversaries if they so choose with no ill feelings at all, as far as I (and I think the majority of my teammates if not all of them) are concerned.
