Error when attempting to use UpdateWeaponSpawnChances

[Bash Kraken]

I'm currently attempting to learn how to use this function, and although my code compiles, it fails when testing ingame.

Here is the code:

public void OnStartup(){
Dictionary<short,int> weaponChances = new Dictionary<short,int>();
weaponChances.Add(17,0);
Game.UpdateWeaponSpawnChances(weaponChances);
}

And here is the error I get when testing it:

Script Error
Error in method 'OnStartup()' in map script. See the exception for more details:
--- Exception ---
Enum underlying type and the object must be same type or object must be a String. Type passed in was 'System.Int16'; the enum underlying type was 'System.Int32'.

Help would be greatly appreciated!

Fixed to the release of SFD.
Doesn't look like Game.UpdateWeaponSpawnChances can be used before the fix.
