The mechanism for how this bug arises is that the *WaypointGenerator* uses the *FlightWaypoint.waypoint_type* to decide whether to generate the waypoint in the .miz file using a *DeadIngressBuilder* or a *SeadIngressBuilder*. This *waypoint_type* is set by *ato.flightplans.<sead|dead>.Builder*, which is set when *ato.flight* is initialised in the *Flight._flight_plan_builder* member variable based on *Flight.flight_type*. When *Flight.flight_type* is updated when the flight is changed from SEAD->DEAD, *Flight._flight_plan_builder* is not updated in the development build, resulting in it continuing to generate SEAD waypoints. This PR adds *set_flight_type()* which sets the *flight_type* property and updates *Flight._flight_plan_builder* and uses this function when converting flight types. Ideally, *flight_type* should be made private and only accessed through getter/setter functions that encapsulate this behavior, but that would mess up any existing liberation save files. This PR was tested by: 1. Opening the save file from Issue 2779 in the development build 2. Clicking "Take Off" and confirming that the Weapon Release Type is "Guided" at the Ingress Waypoint as described in the issue. 3. Opening the save file from Issue 2779 in this PR 4. Converting the SEAD2DEAD flight from DEAD back to SEAD, and then from SEAD to DEAD 5. Clicking "Take Off" and confirming in the mission editor that the SEAD2DEAD flight has Weapon Release Type set to "Auto" at the Ingress Waypoint.

About DCS Liberation
DCS Liberation is a DCS World turn based single-player or co-op dynamic campaign. It is an external program that generates full and complex DCS missions and manage a persistent combat environment.
Note that DCS Liberation does not support the stable release of DCS. We can only guarantee compatibility with either the open beta or the stable release, and more people play the open beta. DCS stable might work sometimes, but it's untested, and we will be unable to fix any bugs unique to stable DCS.

Special Thanks
First, a big thanks to shdwp, for starting the original DCS Liberation project.
Then, DCS Liberation uses pydcs for mission generation, and nothing would be possible without this. It also uses the popular Mist lua framework for mission scripting.
Excellent lua scripts DCS Liberation uses as plugins:
- For the JTAC feature, DCS Liberation embeds Ciribob's JTAC Autolase script.
- Walder's Skynet-IADS is used for Integrated Air Defense System.
Please also show some support to these projects !
