I have noticed one little problem.
If you talk via rcon (using HLSW) it causes an error.
[SM] Native "GetClientIP" reported: Client index 0 is invalid
[SM] Displaying call stack trace for plugin "savechat.smx":

Guess it's nothing to worry about as the plugin keeps on working fine.
Just thought I would point it out, as there are "certain" times where you have to talk to players on the server.
