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?

Hello! Love this mod, this is such great work! Is there any way to download older editions? There are a plethora of mods by amazing authors I wan't to use that are no-longer compatible and sio many of them ahven't updated anything since 2019. Preferably version 3.2.2, as that seems to be the version most commonly cited on Nexus.

Best mod ever

Hello there, I'm having problems when I want to change the graphics in the game, when I change them from "Large" to "Medium" and close the game, as indicated by the box that appears after making those types of changes, when starting the game The changes you have made return to their original state. I've already tried changing the New Vegas graphics instead of TTW but the problem persists. I've been looking for guides on how to fix this for a while but none of them help me so far. I would like to know if there is a reason for this and if it can be fixed, thank you very much.

Can't find any answer to this: I'm on Linux, and I don't see any reason why I shouldn't be able to manually and natively encode the files to ogg myself instead of running oggenc2.exe. Is this possible? I'm wondering if it might work better/go faster than doing it through Wine.

Best mod for new vegas

I just installed the mod through MO2, but it doesn't show a Tale of Two Wastelands executable in the list. I'm not sure how to proceed from here.

What's the diference between the two i nstallers that came up in this mod ?

Im not a very experienced modder/mod installer so it may just be my incompetence but I dont have a file called update.bsa for NV?? I have steam copies of both NV and 3, so it may just be a steam error or I forgot a critical file.

I'm confused about the recent activity on the installer. It was uploaded on 27 May 2024, but the changelog is much older than that. The version number is also the same as it has been for a while, so I'm not sure if this is a change to the installer, the content of the mod itself, or neither. Where might I find this information?
