I don't know. I just work with the english version. Zbyl does whatever it is that's needed to make it work on non-english versions. And several issues you list have indeed long been fixed. Might be he forgot to add have 005EBO installed for French people, so it's an issue with the installer.
It's always a sad day when I am right 0_0...
Which one? Some might be an issue, like the Dxun one from the my unofficial patch since it got erased from the dialog.tlk so potentially not translated, and obviously, Kaevee. What else?
If that was the case we would just keep it english only, like 1.4 was. I don't know why the french version of 1.7 has so many issues that are already fixed by the english version, and quite possibly, all other nationalities.
Well, for the full version ask Stoney, but from what I gather Atton doesn't have this animation. His pre-fab has. However that one can't change clothing and usuing actual Atton (with actual clothing) will break the scene since the animation is mission.
Know about the black screen issue on Dantooine when using modified Kreia skins? Something like that. It's the joys of the Aurora engine...
They do that for the bigger action sequences or special sequences, like T3's intro/tutorial, RE fight, Sith boarding fight, the switch to 950COR cutscene, Hanharr/Mira joins cutscene etc.
For example in the last 2 if you break that convo and end up in the module, you notice there is a LOT of EH lacking... just the parts that are used for the scene are used. There are about 12 such modules IIRC, 003EBO (obviously) being the biggest and most crowded one.
That's not 003EBO, so not a 'legitimate Ebon Hawk', as you like to call it. What makes 005EBO so 'unlegitimate'?
