i dont know if this helps you in any way regarding the developement, but just in case i wanted to report this.
i was killed on experimental server uk 0-10 in the time between 18:30-19:00 CET, 18th of aug 2015 at bor, managed to return there in time to meet the player. i was shouting at him - being a bit upset - then he seemed to use some kind of "speed - hack", moving with approximately tripel-speed looking like a slideshow and disappearing after even faster. My guid is bde3a3eac12f6aef270828054e660b0a.
