When players are lagging, his/her stat.timeSinceDeath update slow/irregular(example below).

For example, I run a server on my computer. I connect using 127.0.0.1, and when someone else joins using the port forwarded IP, he/she has of course has server lag due to connection stability. The client apparaently sends the amount of ticks since last dead, which can be annoying for tracking players, or having a leaderboard for players that are alive the longest.

Solution would be that the server updates this stat, so it's reliable and doesn't get out of sync.

Thanks, this would save my map!
