Hello!
I had 50 skill points, "SC Multiplier X10," and "Non-Boss SC Multiplier X10." I went to buy "200% more RC on Reset." Nothing happened. I thought, maybe it wants me to buy "Boss SC Multiplier X15" as well. So, I tried to buy it. Nothing happened. Let the game sit for a while. Nothing. Refreshed the page and ended up with the screenshot attached.
I could understand -25, but -75! Haha, definitely some goofy bugs around still.
