I am seeing these in the client console:

Code:

ConVarRef z_versus_wandering_density doesn't point to an existing ConVar

I think someone is flooding the server with invalid StartGestureSceneEvent to cause massive lag (3000ms+). Is there anything that can be done about it? This happens on official servers too.

Thanks.
