Nuka World has no height data, because, maybe the developer’s PC was a potato like mine?
This fixes the height data for the main worldsapce “NukaWorld”
This should allow VBs to fly around NukaWorld.
Vertibird mod not included. I suggest my own mod: ZSZ Free Vertibird.
File: zsz_heightdata_nuka.esp
NB currently ZSZ Free Vertibird also requires a patch to enable Nuka World.
