Hmm, I am unable to recreate the issue.
- Enable the Blueprint Resources setting
- Selected a resource
- Place Resource mining drills
- Create the blueprint
- Place the blueprint, it should place the drills and the resource
The drill ghosts will be blue when attempting to place the blueprint, and that is expected. The blueprint will work as expected when placed.
Once the blueprint is created, it will always behave as it was created. Changing the startup setting after a blueprint is made, does not change how that blueprint works.
