@Jonathande What the junk? You're right. I saw your comment and went to the cube store and clickity click I saw my cubes disappear into the void on previously maxed cube upgrades. Definitely a bug there.
what if you put a counter/timer system on all the achievements so we could know how long it will take till a certain achievement is gained. for example: based on the rate of stone being produced, how long would it take for you to achieve 1200 stone?
