Same PCG, different outcome

I have two PCG’s to create a path that are 100% equal except for the selection and transform of assets. Both use the same selection script from their own level setting:


but where one does exactly what it should do - namely place the path onto the landscape:

the other places the path WAY below the surface:

If I disable the projection node for that landscape, I can place it onto the surface:

where the asset’s pivot point in the same as the other script.
It happened after I made some changes in the level, but none had to do with this pivot location. I cannot change it either.
