You don't need to use
FCVAR_PLUGIN in your convar. That FCVAR literally does nothing (even says so
in the include). It was the first thing I noticed when I viewed the source code of this plugin;
My
syntax highlighting highlights old syntax/deprecated/unused things red.
Also, I had
no clue that this
sv_rollangle convar existed, nor that setting it to such an insanely high value would cause this. How did you figure this out?
