Simply make a ghost on a space platform for a machine with modules Then go to the platform hub and check "Auto request missing construction materials": As you can see it does not request the modules, however it will do so once the building is built.
This is incredibly annoying as I use this feature to work out how many materials I need to send over (using it to *automatically* send over construction materials however is totally useless though unless you have a full rockets worth of the material...).

I've also had this happen with other items (notably belts), but I don't know how to reproduce that issue.

Thanks for the report. That is correct, they will be requested when the building is built.

A workaround for your use-case might be to use a dedicated upgrade planner to count them ?

Will that also count non-ghost modules though?
I could always use the blueprint tool to get the total count,
deconstruct all the ghosts (I have a deconstruction planner that only tpuches ghosts), then use the blueprint tool again to see how many modules are in use, then control-z to put the ghosts back.

Or I could just manually count them.
