Swep Error DarkRP 6.0

Hello, i have a DarkRP Server 6.0, and i get Spamming with:

“SWEP:SetWeaponHoldType - ActIndex[ “” ] isn’t set! (defaulting to normal)”

I Have no SWEP,

it happens, by joining people,
or Job change …

anyone can Help me thx …

Sry for my Bad Englisch …

One of your SWEPs uses SetWeaponHoldType instead of SetHoldType
