Tale of Two Wastelands


I have a problem.
I'm on TTW 3.3.2. perfectly installed and working fine and smooth till the "Take It Back" quest in FO3 branch.
Even if I have a custom race it worked fine by the Player side because I have a mod that fixes the custom races problems and it results in my char awakening in the Citadel in front of Elder Lyons as expected.
The problem is with Fawkes:
1. I have chosen to let Fawkes inside the Airlock and he agreed and ran toward the Airlock ... BUT:
2. The scene with Fawkes activating the Purifier never started.
3. Instead it started the Final Cinematic (the correct one with Fawkes inside) of the End of the Main Quest.
4. At its end there was the classic loading screen and then the scene with Elder Lyons, my char and Sarah in coma state.
5. Fawkes is NOT nearby.
6. I searched him and found him on the Jefferson Memorial's catwalk walking few steps forward and back endlessly.
7. Trying to "disable" and "enable" him by console returns that he's locked with a package like: "DLCxxMQ11FawkesCodeWaitForAirlock".

So it seems that this part of the MQ11 quest is never completed even if the quest itself is finished (as per on screen message at the Citadel).

I tried almost everything to restore Fawkes but with no result.
What can I do now?
