I'll double check the Research Pages (Resurface) and the Preview Page to make sure the buttons are displayed properly and working as intended. There was a few issues with wording in the menus that I did not convey properly to players. As far as the negative RNG, that brings up a good point. Would the problem be made less severe if the cost of crafting pickaxes was reduced? 2 or even 1 Ingot per attempt, then increasing the cost of Ranking up pickaxes so the cost is the same. That way you can get a good early start power roll without investing too much, then you can pick which one to craft your EXP into. I'll be analyzing and adjusting this system as we continue testing. Thanks again for your feedback!
