Honestly, no idea what you mean by that including shuttle through 2 floors...

When you launch a shuttle to a map and choose where you want to land it, you can choose a building which has a roof, right? Well this mod adds those vac roofs which don't get damaged.

But multi floors gives you the ability to make a room over a room AND if you launch a shuttle into the bottom floor, it's gonna destroy the roof of the bottom room and the top room, now with vac floors it should not destroy them. But it does, not on the bottom floor but on the top one.

It is meant to not get damaged but it seems to only turn off when a shuttle is approaching that floor and doesn't check if any of the floors bellow are expecting a shuttle, meaning that the bottom floor vac roof will allow the shuttle to pass without issue but the floors above them even with vac roofs still get damaged and destroyed

Sounds like something that needed to be implemented in multi layer mod, rather than here. Such mod rewrite vanilla game pretty drastically, so implementing a solution for such should be there as well. After all from what I understand they already implemented way for shuttles to pass through multiple layers, so they adjusted shuttle landing logic. All it now takes for them is do simple check whenever it vac roof with a compatability patch. Which pretty simple by using CO method IsVacRoof(). Implementing it within their patches for skyfaller would make more sense, than CO patching their patches for patch changes...

Could you maybe then talk with that mods creator about how you implemented it in here? You know your mod way better than anyone else so I believe there is a greater chance of it working out

Sure, you can ask them, if they want add such. They can always reach me through here or discord, if they need help regarding what to do.
