I get what you mean now, and yes, I made the mistake of thinking that picking a specific stat and sticking to it throughout the game would be intuitive, but it doesn’t seem so. I’ll keep that in mind for both the DLC and future projects in general.
Nevertheless, I lowered the threshold of stat points needed and re-uploaded the game, now it should be much easier to pass the stat locks even without the guide, should be possible to unlock both, too. Hope that helps, but if it doesn't let me know and I'll make further adjustments. I'll also update the 65 page of the guide within the next hour, or so.
