I have rolled back SourceMod and a lot of other stuff is now working.
What I did notice was that I cam play as long as I like with Bots on the server...
"sv_cheats 1" then "bot" three times. The mod is rock solid.
But, the first time I had a person join... as soon as he killed me the server crashed, the last stroke of his shovel... bang... hard crash. I was the last allied player, the three bots were dead.
Using MetaMod:Source v1.6.2.703V, SourceMod v1.1.$PREVISION.2339 Windows server.
Tried again, 3 bots and I allied, another player joined, he slayed me ok (the bots were still alive) , I got put on to the axis side, while in spawn, myself and the other player got this message...

The server stayed up, but every time myself and the other player went to the server, as soon as we seleted a team we crashed our client PCs with that message and the server remained up... no one could join it until I changed the map via HLSW.
Hope this helps.
