You might want to make it dependent on having the blueprint tech unlocked. It happily marks things for deconstruction without the tech but that's all it can do. Removing the deconstruction flags without a deconstruction planner is not simple (I just reloaded since it was a test).

Right, that makes sense. I'll have to add a technology to research it.

That or just add it as a result of doing the blueprint one?

Hmm. I can do that, it is less work i guess. However i need to manipulate a tech that exists and that might collide with other mods.
