Define the loading order of installed packages

[FlyingRaccoon]

<PackageOrderHint>, as a child component of <AssetPackage>.
So in your case, something like:

<AssetPackage>
...
   <PackageOrderHint>CUSTOM_NAVDATA</PackageOrderHint>
...
</AssetPackage>

I’ll make sure the documentation is updated accordingly.
