So i needed a some heavy >light oil convertins
So i just blueprinted my light>petrol build. and pasted it again.

Then i would expect its just a matter of changing the recipe, and connect the pipes.
But even whitout any fluid in it (pipes are not connected to anything),
i cant change the recipe because i get a " cant mix fluids warning"

All connected buildings are checked to see if fluids would be mixed, not just pipe contents.

This is intended behaviour, you can either omit the last pipe to the producing entity in the blueprint or create dedicated blueprints. NaB.
