Because Bethesda would shut down that mod so fast. I believe that Bethesda owns the docs for Van Buren. Which explains them using some of Van Buren's designs for Fallout Seventy Shit.

But Bethesda is usually okay with mods like that. If Bethesda is okay with mods like Fallout 4: new vegas, skywind, and skyblivion, and source port project like daggerfall unity, OpenMW, and fallout online engine then I don't see why Bethesda would shut down a van buran mod.

I'm not surprised. If the poor modders get something 1% inaccurate with their version of Van Buren, maybe use a tile from the FO3 asset pack, the community will shit on their thread and insult them
