Someone joined my server and wrote in chat:
which instantly crashed my server.

Heres a dump: https://crash.limetech.org/gvx4efbin3w3

Is that a sourcmod or a problem from one of my plugins?

Update 2:
This odd line is mention in a steam community thread here:

I'm still at work, but maybe one of my admins can test that.

Update:
One of my admins tryed that out on our test server. He tryed it via chat and via conole and it didn't crash...hmmm...

Nvm the odd line. It did crashed on other entries too. I rolled back an update i made for a plugin which uses
Code:
AddCommandListener(Command_Say, "say"); AddCommandListener(Command_Say, "say2"); AddCommandListener(Command_Say, "say_team");
There are a few "else ifs" for "!" commands which arent actually registered console commands (RegConsoleCmd) like
Code:
else if(StrEqual(text, "!edlogo", false) && IsPlayerAdmin[client])
That line above for some reason made the crash, even though people were not typing that in. After I removed that (which was the only change since weeks) it was fine. Coincidal there were other crashes too which are gone after that, crashes like these: https://crash.limetech.org/4chkkzdc5kdn

Can you attach the full plugin? I'd like to reproduce this.
