I can't seem to get the "Coin progress" upgrade. It says it's 100k, and I have more than enough, but nothing happens when I click it.
usually with these things internally some odd number like 123,456 is needed but for displaying , the number is shown rounded down to for example the next closest 100k step.
so 123,456 is rounded down to 100k, so 100k is displayed. but none the less 123,456 is needed so having a flat 100000 isnt enough :-)
