I'm working on a Mod, and have hit a problem: the Code below kills my SCript the moment the required Weapon is Drawn. By this, I mean that the Script completely stops running-- the Quest is still active, but none of the variables update, and even Messages do not display in the Console/Top Corner of the screen...
Removing this Code fixed the problem, so it seems to be the issue...

;	If ( ReaverEquipped == 1 );		Set CannotHarm to 0;	ElseIf ( ReaverEquipped == 0 );		Set PlayerWeapon to ( Player.GetEquippedObject 16 );		If ( PlayerWeapon.GetIsID ZCDMSRReaver01 == 1 ) ; This triggers the error.;			Set CannotHarm to 0;		ElseIf ( PlayerWeapon == 0 );			Set CannotHarm to 0	;		Else;			Set CannotHarm to 1;		EndIf;	EndIf

CannotHarm is a Variable that has no effect in this Script, it's only used by an Item Script later to check if the Weapon/PLayer's fists are equipped.

GetIsID is used to check if the calling reference is from a given base Object and must be called on a reference FormID (items in containers and inventories don't have reference FormIDs).

GetEquippedObject alredy returns a base object FormID, so you may just check if it is the object you want ("if PlayerWeapon == ZCDMSRReaver01")

GetEquippedObject returns a base object, not a reference, I think, so maybe "if PlayerWeapon == ZCDMSRReaver01"?

Right now, I think you're asking it to do a comparison to the base object of a base object.

edit: okay, my research took too long, but at least I was right about it.
