I'm not seeing this bug, myself. With a fresh install and a fresh game, the BCB research unlocks the iron stick recipe.

I must say, adding the planners to the blueprint menu (and the planner picker menu) is a much, much nicer way of pulling them out of the ether (to the point I'd even suggest unbinding the keybind to cycle through them, which I've always found a bit of a pain given ALT-Q is bound to multiple things).
