Once one finishes SR’s boss wave, one can either continue or “cash out” and herein lies the issue: sometimes, when trying to proceed, i end up pressing “cash out” by accident. Happened twice already with waves just prior to get the blueprints for the next “round of 15”.
Perhaps a bit of extra spacing between the options so that, if one doesn’t click the top one, doesn’t end up clicking the bottom one instead, accidentally.
