Auto Foundations under Railways built in blueprint designer not present in built blueprint
Context: I am on a creative world. In a blueprint designer (I've tested the vanilla designer as well as modded), I use the FUR mod by @Andre Aquila <Aquila Industrial> to build a nice curve. The foundations appear perfectly and seem to save correctly. When loaded via the blueprint designer, the auto-built foundations appear perfectly fine. The problem: When I build the blueprint outside the blueprint designer, the auto-built foundations do not appear. I understand from the mod description that it will not auto-build them from a blueprint, but I thought the foundations saved in the blueprint designer would be built. To illustrate, build a rail in a blueprint designer with the auto-spawning foundations. Delete the rail. The foundations are still present. Save the blueprint, and build it outside of the designer. The foundations are no longer present. As far as I understand, this isn't intended behavior? Or perhaps I've misunderstood the mod description. Either way, I'd like some help with what's going wrong here.
