For some reason cash upgrades have disappeared on me... it was working before but now there is nothing in that screen... I still have the option to quik buy and it buys something but can't actually see anything...
While "experimenting" with your Buy x it has screwed it up... I thought something seemed weird so I did a quick reset... now at 4350 donuts and apparently... 1 more costs 139.291 sexsexagintillion while 10 more cost 131.313... and if I switch to buy max it tells me I can buy 90 at 425.502! Not sure what you guys did to the math but I don't think that adds up quite right xD
