Unassigned Flights taking Assigned Flights' Flight numbers
Description
Flights that weren't assigned a flight number by me are getting another route's flight number, therefore the adopting the pricing assigned to that flight number.
Expected behavior: Unassigned flights should be randomly assigned a number, that is not already assigned to a current flight.
Actual behavior: Some unassigned flights are taking the flight numbers & pricing of assigned flights
Possible Solution: Add a check to the random number code that makes sure the random number generated doesn't already exist
