[1.1.0] Blueprint with burner mining drill can't be flipped

[Kuxynator]

Blueprint can't be flipped. At least if it contains a burner mining drill. Not tested with alle entities.
With burner furnace, burner inserter, wooden chest, and concrete tiles it works.

The mining drill is not symmetrical so this is likely intended.

[posila]

That's correct.

The answer is not satisfactory.
If the building cannot be mirrored, it should still be possible to mirror the blueprint, the building can remain as it is, the position can be mirrored.
It is possible with the mod Blueprint Extension, why not mit the base game?

This was just discussed in the Friday Factorio Facts yesterday:

Blueprint flip Klonan

It was requested a lot over the years, and we always said no. The reason being, well not everything can flip, things like oil recipes, rail signals, pumpjacks etc. Due to these asymmetries, if you flipped a blueprint with these entities, the result would be non-functional in the best case, and cause complete chaos in others.

But then kovarex was playing and really really wanted to just copy and flip his train unloading setup (just your typical Inserters, chests, and belts). So he decided to just add it, and prevented the flip problems by just disallowing flipping blueprints that wouldn't flip properly.

It was a design decision to allow blueprint flipping, but disallow it in the case of non-symmetrical entities.
