I'm trying to hide the following object

Map.hideObject(474, -393.412, -505.822, 9.92519)

This returns the following error:
[error] Event callback error: stack index 2, expected number, received number: not a numeric type that fits exactly an integer (number maybe has significant decimals) (bad argument into 'void(int, short, short, short)')

The game only hides an object if it uses a decimal value, otherwise the object is not hidden.
