eventscripts and shellshock

I friend of mine is working with shellshock mod with eventscripts...running MetaMod ver 1.70 There is an problem with Shellshock...this message comes up EVERY second [SHELLSHOCK] SetCommandClient<> called: index=-1 What's wrong??

Eh Ive run eventscripts on every hl2dm pub that I have ever had that wasnt specifically a CAL server and I have never seen that before.

I have no idea.
