Just to point out I think I found the cause of the many false-possitives in my GMod server. The gamemode had an AFK script which would turn a player into an NPC - It then used:
PHP Code:
Line 63: ply:SetEyeAngles(ply.AFKNpc:EyeAngles())
Line 63: ply:SetEyeAngles(ply.AFKNpc:EyeAngles())
Line 75: ply:SetEyeAngles(ply.AFKNpc:EyeAngles())
Line 75: ply:SetEyeAngles(ply.AFKNpc:EyeAngles())
I'll edit out those and post back if it becomes more stable.
