Absolutely nothing. I just wanted everyone to come back to the mod page to see that an optional file has been added for Nuka-World that should fix the issues people have calling vertibirds there.
Since I have no other way to notify users of optional files, this seemed to be the best way to try.
This is a small mod I came up with while working on a separate project. It allows vertibirds to be called via signal flare (or whatever mod you may use that calls vertibirds using the vanilla quest structure) within other worldspaces.
Note that not all locations are perfect for vertibirds so it may seem odd the way it behaves (ex: Far Harbor) but it definitely works well enough to be worth using IMO.
