This should also happen with the shipment grouping.
So I agree with @pokoli, that the first invoice or shipment instantiated because we did not find an existing one must be saved directly. Of course this will penalize the optimization of issue10801 but only when there is a grouping method (and it was any way reduced by the module which does a search for each sale).
