If a create a blueprint and mirror it, the preview of the blueprint will still show the unmirrored one.

[1.1.0] Blueprint preview not updating after morroring
Re: [1.1.0] Blueprint preview not updating after morroring
Technically this is correct: flip is not changing the blueprint but only setting a non-game-state flag that the blueprint is considered flipped when placing and when it is being placed, action is sent saying "place this but make it flipped". Changing this would literally make the whole logic more complex with no added value and i see no point in doing that. If flip would be required to change blueprint, then the rotation would also have to change blueprint, right? Rotation is not changing blueprint so the flip will also not be changing it.

Sounds reasonable.
