I have found one error.
I use
Super Admin Commands to disarm player entirely all weapons.
So it stand T-position, no weapons and knife.
When try attack/shoot without weapons, plugin print these errors in logs
Code:
L 04/13/2010 - 22:30:49: Info (map "de_dust2") (file "errors_20100413.log")
L 04/13/2010 - 22:30:49: [SM] Native "GetEntPropFloat" reported: Entity -1 (-1) is invalid
L 04/13/2010 - 22:30:49: [SM] Displaying call stack trace for plugin "downloads\weaponmod.smx":
L 04/13/2010 - 22:30:49: [SM] [0] Line 1176, weaponmod.sp::OnPostThink()
But maybe this is not big problem if players not play no-weapons
