The bot restarts several times per day due to backup scripts that I wrote, 16:00 U.S. Eastern is one of the backup times so that's why it was only online for about 45 minutes
As for last stand, b3 does not and will not ever be able to detect it due to how the game engine logs last stand kills (it doesn't). I know this isn't the first time I've said this.
On the other hand, if you see someone with marty running around that is not getting detected, I'd be more than happy to take a look if you have a name and rough timeframe. Just to clarify, the grenade that gets dropped must kill someone for the bot to catch it, the game engine doesn't output log entries for marty drops that don't kill anyone.
Based on the last reply from Striker, it sounds more like this was a concern that last stand wasn't being caught. Unfortunately last stand is something that would require an admin's presence. I did check warnings that have been issued today and b3 has issued several warnings for marty and a couple temporary bans, too.
