It wasn't the limited stopovers in Europe that were the problem as TLV-LHR-MEL and CPH-MAD-TLV were both done with less than 24 hours between flights, so those errors went away.
How are you getting from CDG to CPH?
AFAIK there is no Oneworld service, and if transiting somewhere, that will result in a 5th flight in the continent of origin which is not allowed
EDIT: to remove the rubbish I had in about two visits to Asia (brain is now in gear
