I've installed and run a balance server (benmachine's Balance Mod Server, but it's pretty much only up when I can be bothered to start it) and it all works fine form a gameplay perspective, but I have found a few bugs with the new !slap command: when someone dies of !slap, the console log tells me they were killed by MOD_OVERMIND, and when the console !slaps anyone, we are told that "^3!slap: ^7UnnamedPlayer^7 feels ^7_ACIDTUBE^7's authoritay\n"
Plus I seem to be getting <world> killed player by MOD_TESLAGEN messages when they were actually gunned down by a turret. Out of curiousity I asked some players to build me a tesla and kill with it, and I was told the killer was MOD_HSPAWN
In the game, everything seems to be normal, but the console turns up all the wrong messages.
edit: also if you !slap someone as a spectator while following them you get the self-flagellation message.
