Blueprints do not follow the current level of technology

[Sherman]

Hey.
I found that if you start building a conveyor belt according to a blueprint that uses logical wires. Then in a game in which the technology of combinators is not yet open, sensors on the conveyor belt are still installed using logical wires. But the level of technology does not yet allow the player to have logical wires.

Can't find the original, but this has been declared to be working as intended.
